QUESTIONS 1-400 Q.1 Electrolytes are best defined as: A) Vitamins that dissolve in water B) Minerals that help maintain the body's fluid balance C) Proteins that regulate metabolism D) Carbohydrates that provide quick energy Correct Answer: B Rationale: Electrolytes are minerals (such as sodium, potassium, and chloride) that carry an electric charge and are essential for maintaining fluid balance, nerve impulse transmission, and muscle contraction in the body. Q.2 Which vitamins are classified as water-soluble? A) Vitamins A, D, E, and K B) B vitamins and vitamin C C) Vitamins A and C only D) Vitamins D and E only Correct Answer: B Rationale: Water-soluble vitamins include the B-complex vitamins (thiamin, riboflavin, niacin, B6, folate, B12, biotin, pantothenic acid) and vitamin C. These vitamins dissolve in water and are not stored in large amounts in the body. Q.3 Linoleic acid is best described as: A) A saturated fatty acid found in animal products B) An essential polyunsaturated fatty acid of the omega-6 family C) A trans fatty acid created during hydrogenation D) A monounsaturated fatty acid found in olive oil Correct Answer: B Rationale: Linoleic acid is an essential omega-6 polyunsaturated fatty acid that must be obtained from the diet because the body cannot synthesize it. It is found in vegetable oils, nuts, and seeds. Q.4 Alpha-linolenic acid is classified as: A) A saturated fatty acid B) A monounsaturated fatty acid C) A polyunsaturated essential fatty acid in the omega-3 family D) A trans fatty acid Correct Answer: C Rationale: Alpha-linolenic acid (ALA) is an essential omega-3 polyunsaturated fatty acid found in flaxseed, walnuts, and some vegetable oils. It must be consumed in the diet. Q.5 The bran of a grain kernel is: A) The innermost part containing starch B) The outer protective covering that is a good source of vitamins and fiber C) The part that contains most of the grain's protein D) The small structure at the base rich in fats Correct Answer: B Rationale: Bran is the outer protective covering of the kernel and is an excellent source of fiber, B vitamins, and minerals. It is removed during refining of grains. Q.6 The endosperm of a grain kernel: A) Is the outer protective layer B) Contains most of the grain's carbohydrates and protein C) Is rich in healthful fats and vitamins D) Is the inedible husk Correct Answer: B Rationale: The endosperm is the grain's midsection and contains most of the carbohydrates (starch) and protein. It is the primary component of refined grains like white flour. Q.7 Hydrochloric acid in the stomach functions to: A) Emulsify fats B) Activate pepsin C) Absorb vitamin B12 D) Neutralize stomach acid Correct Answer: B Rationale: Hydrochloric acid (HCl) activates pepsinogen to pepsin, which is essential for protein digestion. It also destroys bacteria and makes minerals more soluble for absorption.
