The Use of Computers in life 3. Read the following passage and then answer the questions below: 10 marks Vitamin research may be the fastest growing area of research in medicine.

Despite the fact that the public apparently trusts vitamins to do exactly what their manufacturers say they will do and rushes to buy vitamins, there are a great many misunderstandings and myths about what vitamins are and how consumers should use them. And research is consistently proving 1hese myths wrong.

First of all, many vitamins simply will not do what is often claimed. Vitamin C has never been proven to aid in the prevention of colds.

B vitamins do not get rid of "the rundown feeling"; any effect a person feels when taking a capsule, for example, is purely a psychological effect. B deficiencies are rare, and even in cases where B treatment is necessary, the vitamin must be injected because it is ineffective when taken orally. Vitamin E is often said to prevent heart disease, improve virility, and slow the aging process, but there has been no experimental proof of any of these claims.

The fact that male rats become sterile when deprived of vitamin E does not mean that the same thing happens to humans who are deprived of E. In fact, it is nearly impossible to study vitamin E deprivation in human beings because vitamin E is present in almost all sourcesofhuman fuod. The same is true of almost every other vitamin. They are abundantly present in a balanced diet. The most common vitamins are A, B-1, B-2, C, and D; and if a person eats a balanced diet that provides these vitamins, all the other vitamins will be present in enough quantity.

Though many people claim that vitamins are rare and that you should eat special fuods or take vitamin pills daily to make sure you are getting the correct quantity, this is simply not true.

In fact, you can overdo vitamin supplements. Some vitamins are toxic if you take in too much of them. Vitamin C overdose can cause diarrhea and kidney stones. Large amounts of A can cause pressure to build up in the brain or cause dryness in the skin, headaches, general pains.

Vitamin D overdoses can cause mental and physical retardation, nausea, and high blood pressure. In fact, vitamin overdose is often more severe than vitamin deficiency and is becoming more common.

Another myth about vitamins is that "natural ones are superior to those produced in the lab. People will often pay high prices for vitamins made up of natural ingredients--such as C from rose hips--when synthetic, lab-produced vitamins are available at much cheaper prices.

In fact, a vitamin always has exactly the same molecular structures whether its source is a plant, animal or test tube; any change in its structure would make it a different substance altogether. There is not any difference between a synthetic and a "natural" vitamin, so the body cannot possibly make a distinction between the two.

Circle the correct answer: 1. A good title for this passage might be a The Dangers of vitamin overdose b. Vitamins c. Myths about vitamin supplements d.

Natural and synthetic vitamins 2. The main idea of this passage is that a. The passage states that a most vitamins are not effective when taken orally. Slowing the :aging process" has been associated with a. Which of the following conc1usions does the passage support? The author probably a is a vegetarian. As used in this passage, the word virility means a.

Translate the following into Arabic: 10 marks When you were a youngster and couldn't sleep, your mother probably told you to drink a glass of warm milk; if she did, the folk remedy she prescribed had a scientific basis. The amino acids contained in milk have a sedat1ve effect; various amino acids found in high protein foods promote heavy, relaxing sleep.

So, if your mother really-wanted to make sure you got plenty of sleep, the warm glass of milk should have been preceded or accompanied by a high protein dinner of meat and cheese. Grammar: 10 marks A. Correct the verbs in brackets 1. He not buy the book if he does not want it. He come if you had asked him. If I have to go to London, I will learn English.

University Life Read the following passage and then answer the questions below: 15 marks Blood pressure is created by the heart as it pumps the blood through the circularity system. The pressure is not constant but varies with the action of the heart.

The higher pressure, called the systolic, occurs when the heart contracts; and the lower pressure, called the diastolic, is the pressure remaining in the veins, when the heart relaxes. A systolic pressure over or a diastolic pressure over 95 is considered "high blood pressure. Because the blood pressure can vary as a result of excitement, stress, or sleep, most doctors will measure blood pressure several times before deciding that a patient is suffering from high blood pressure.

Unless the pressure remains at high levels, there is no cause for alarm. Everyone's blood pressure "goes up" sometimes. Choose the correct answer: 1. The main purpose of this paragraph is to a. Diastolic pressure measures a. We can conclude from the paragraph that a.

The paragraph suggests that a. As used in this paragraph. The word stress means a. Translation: 9 marks Translate the following into Arabic: Years ago, polio was a common disease among young children and often left its victims with paralysis.

Zaher khafagy 7. Stroma in chloroplasts - mitochondria is similar to matrix in chloroplasts - mitochondria ; they both accommodate biochemical reactions. Thylakoid membranes resemble cristae; they both contain electron transport components - photosynthetic enzymes - chlorophylls. Cytochromes are electron carriers in mitochondria only - chloroplasts only - mitochondria and chloroplasts. Ferridoxins are proteins conjugated with iron - cupper - magnesium.

Respiration starts by glycolysis in the mitochondria - cytosol - chloroplasts. Release of respiratory C02 takes place in the mitochondria - cytosol - chloroplasts. Oxidation of pyruvate into acetyl CoA is a transition reaction linking glycolysis to Krebs cycle - Calvin cycle - oxidative phosphorylation. Carotenoids exist in the thylakoid membranes - stroma -lumen.

Carotenoids are absolutely stable because of their isoprenoid structure - their yellow or red color - both. Each molecule of carotenoids - chlorophyll - cytochrome contains one single magnesium atom. Glycolysis - Light - Dark reactions of photosynthesis are independent on the presence of light.

Two - Three - Four electrons release per each oxygen molecule evolved in photosynthesis. Enzymes accelerate - start up - inhibit cellular reactions. Each polypeptide chain contains one - two - multiple active center s. Enzymes resemble catalysts as they both lower the energy of activation - act under physiological conditions of temperature, ph, etc.

Read the following passage and then answer the questions below: 10 marks Vitamin research may be the fastest growing area of research in medicine. Despite the fact that the public apparently trusts vitamins to do exactly what their manufacturers say they will do and rushes to buy vitamins, there are a great many misunderstandings and myths about what vitamins are and how consumers should use them.

And research is consistently proving 1hese myths wrong. First of all, many vitamins simply will not do what is often claimed. Vitamin C has never been proven to aid in the prevention of colds. B vitamins do not get rid of "the rundown feeling"; any effect a person feels when taking a capsule, for example, is purely a psychological effect.

B deficiencies are rare, and even in cases where B treatment is necessary, the vitamin must be injected because it is ineffective when taken orally. Vitamin E is often said to prevent heart disease, improve virility, and slow the aging process, but there has been no experimental proof of any of these claims.

The fact that male rats become sterile when deprived of vitamin E does not mean that the same thing happens to humans who are deprived of E. In fact, it is nearly impossible to study vitamin E deprivation in human beings because vitamin E is present in almost all sourcesofhuman fuod. The same is true of almost every other vitamin.

They are abundantly present in a balanced diet. The most common vitamins are A, B-1, B-2, C, and D; and if a person eats a balanced diet that provides these vitamins, all the other vitamins will be present in enough quantity. Though many people claim that vitamins are rare and that you should eat special fuods or take vitamin pills daily to make sure you are getting the correct quantity, this is simply not true.

In fact, you can overdo vitamin supplements. Some vitamins are toxic if you take in too much of them. Vitamin C overdose can cause diarrhea and kidney stones. Large amounts of A can cause pressure to build up in the brain or cause dryness in the skin, headaches, general pains. Vitamin D overdoses can cause mental and physical retardation, nausea, and high blood pressure.

In fact, vitamin overdose is often more severe than vitamin deficiency and is becoming more common. Another myth about vitamins is that "natural ones are superior to those produced in the lab. People will often pay high prices for vitamins made up of natural ingredients--such as C from rose hips--when synthetic, lab-produced vitamins are available at much cheaper prices.

In fact, a vitamin always has exactly the same molecular structures whether its source is a plant, animal or test tube; any change in its structure would make it a different substance altogether. There is not any difference between a synthetic and a "natural" vitamin, so the body cannot possibly make a distinction between the two.

Circle the correct answer: 1. A good title for this passage might be a The Dangers of vitamin overdose b. Vitamins c. Myths about vitamin supplements d.

The pressure is not constant but varies with the action of the heart. The higher pressure, called the systolic, occurs when the heart contracts; and the lower pressure, called the diastolic, is the pressure remaining in the veins, when the heart relaxes. A systolic pressure over or a diastolic pressure over 95 is considered "high blood pressure. Because the blood pressure can vary as a result of excitement, stress, or sleep, most doctors will measure blood pressure several times before deciding that a patient is suffering from high blood pressure.

Unless the pressure remains at high levels, there is no cause for alarm. Everyone's blood pressure "goes up" sometimes. Choose the correct answer: 1. The main purpose of this paragraph is to a. Diastolic pressure measures a. We can conclude from the paragraph that a. The paragraph suggests that a. As used in this paragraph. The word stress means a.

Stroma in chloroplasts - mitochondria is similar to matrix in chloroplasts - mitochondria ; they both accommodate biochemical reactions. Thylakoid membranes resemble cristae; they both contain electron transport components - photosynthetic enzymes - chlorophylls. Cytochromes are electron carriers in mitochondria only - chloroplasts only - mitochondria and chloroplasts.

Ferridoxins are proteins conjugated with iron - cupper - magnesium. Respiration starts by glycolysis in the mitochondria - cytosol - chloroplasts. Release of respiratory C02 takes place in the mitochondria - cytosol - chloroplasts.

Oxidation of pyruvate into acetyl CoA is a transition reaction linking glycolysis to Krebs cycle - Calvin cycle - oxidative phosphorylation. Carotenoids exist in the thylakoid membranes - stroma -lumen. Carotenoids are absolutely stable because of their isoprenoid structure - their yellow or red color - both.

Each molecule of carotenoids - chlorophyll - cytochrome contains one single magnesium atom. Glycolysis - Light - Dark reactions of photosynthesis are independent on the presence of light. Two - Three - Four electrons release per each oxygen molecule evolved in photosynthesis. Enzymes accelerate - start up - inhibit cellular reactions. Each polypeptide chain contains one - two - multiple active center s. Enzymes resemble catalysts as they both lower the energy of activation - act under physiological conditions of temperature, ph, etc.

ATP synthesis can be driven by light energy only - food oxidation - light energy or food oxidation. The substrate of Rubisco is ribulose 1,5 bisphosphate - oxaloacetic acid - glyceraldehyde 3 phosphate Organisms lacking chlorophyll a - chlorophyll b - carotenoids cannot perform ph otosynthetic activity.
