1. The number of kilocalories provided by a food that contains 22g of fat is:

• A. 88
• B. 132
• C. 154
• D. 198

Correct answer: D

Rationale: The correct answer is D. Fat provides 9 kcal per gram, so 22 grams of fat will provide 198 kcal (22g * 9 kcal/g = 198 kcal). Choice A (88) is incorrect because it miscalculates the kcalories. Choice B (132) is incorrect as it does not consider the correct kcaloric value of fat. Choice C (154) is incorrect as it also does not calculate the kcalories accurately based on the fat content.

2. What is the process of converting glycogen to glucose called?

• A. Glucogenesis.
• B. Glycogenolysis.
• C. Glyconeogenesis.
• D. Gluconeogenesis.

Correct answer: B

Rationale: The correct answer is B: Glycogenolysis. Glycogenolysis is the process of breaking down glycogen into glucose. Choices A, C, and D are incorrect. Glucogenesis (choice A) is not a term used in biochemistry. Glyconeogenesis (choice C) refers to the synthesis of new glucose molecules from non-carbohydrate sources, not the breakdown of glycogen. Gluconeogenesis (choice D) is the process of producing glucose from non-carbohydrate sources, not the breakdown of glycogen.

3. After absorption, the end products of carbohydrate and protein digestion enter the:

• A. enterohepatic circulation.
• B. gastrointestinal circulation.
• C. common bile duct.
• D. portal blood system.

Correct answer: D

Rationale: The correct answer is D: portal blood system. After absorption, carbohydrates and proteins are transported via the portal blood system to the liver for further processing and distribution to the rest of the body. Choices A, B, and C are incorrect. Enterohepatic circulation refers to the recycling of compounds between the liver and the intestines, not the direct route for absorbed nutrients. Gastrointestinal circulation is a vague and non-specific term, not specifically related to the transport of absorbed nutrients. The common bile duct is involved in transporting bile from the liver and gallbladder to the small intestine, not the end products of carbohydrate and protein digestion.

4. How does a nursing infant receive antibodies from its mother?

• A. Through anabolism and catabolism.
• B. Through the absorption of antibodies.
• C. Through the absorption of amino acids and synthesis of antibodies.
• D. Through genetic inheritance.

Correct answer: B

Rationale: A nursing infant receives antibodies from its mother through the absorption of antibodies present in breast milk. Choice A is incorrect as anabolism and catabolism refer to metabolic processes, not the transfer of antibodies. Choice C is incorrect as the infant does not need to synthesize antibodies but directly receives them. Choice D is incorrect because while genetic inheritance plays a role in the immune system, in this case, the direct transfer of antibodies occurs through breast milk.

5. Which of the following is an example of a complete protein?

• A. Milk
• B. Soy
• C. Sesame seeds
• D. Sweet potato

Correct answer: A

Rationale: The correct answer is A, Milk. Milk is considered a complete protein as it contains all the essential amino acids required by the body. Soy (choice B) is also a complete protein, containing all essential amino acids. Sesame seeds (choice C) and sweet potato (choice D) are not complete proteins as they lack one or more essential amino acids needed by the body.
