1. Consuming 30 g of which nutrient would provide the highest number of kcalories?

• A. Carbohydrates
• B. Fat
• C. Protein
• D. Micronutrients

Correct answer: B

Rationale: The correct answer is B, 'Fat.' Fat provides 9 kcalories per gram, which is more than carbohydrates and proteins that provide 4 kcalories per gram each. Therefore, consuming 30 g of fat would yield a higher number of kcalories compared to the same amount of carbohydrates or proteins. Micronutrients do not significantly contribute to kcalories, making them an incorrect choice in this scenario.

2. Which of the following is an example of a disaccharide?

• A. Glucose.
• B. Fructose.
• C. Galactose.
• D. Maltose.

Correct answer: D

Rationale: The correct answer is D, Maltose. A disaccharide is formed when two monosaccharides are joined together. Glucose, fructose, and galactose are all monosaccharides, not disaccharides. Therefore, they are not examples of disaccharides.

3. Which term describes the amino acids that are synthesized by the body?

• A. essential amino acids.
• B. nonessential amino acids.
• C. complete amino acids.
• D. incomplete amino acids.

Correct answer: B

Rationale: The correct answer is B: nonessential amino acids. Nonessential amino acids can be synthesized by the body, so they do not need to be obtained through the diet. Essential amino acids, choice A, must be obtained from the diet because the body cannot produce them. Choices C and D, complete and incomplete amino acids respectively, do not accurately describe the classification of amino acids based on synthesis by the body.

4. A characteristic of saturated fats is that they are:

• A. mostly found in animal products.
• B. solid at room temperature.
• C. composed of many double bonds.
• D. found primarily in vegetable products.

Correct answer: A

Rationale: The correct answer is A: 'mostly found in animal products.' Saturated fats are primarily found in animal products such as meat, dairy, and eggs. They are typically solid at room temperature. Choice B is incorrect because saturated fats are solid at room temperature, not liquid. Choice C is incorrect because saturated fats do not have double bonds; they have single bonds between carbon atoms. Choice D is incorrect because saturated fats are mainly found in animal products, not vegetable products.

5. Which hormone prevents excessive gastric activity?

• A. Gastrin
• B. Enterogastrone
• C. Secretin
• D. Cholecystokinin

Correct answer: B

Rationale: The correct answer is Enterogastrone. Enterogastrone is a hormone that inhibits excessive gastric activity by slowing down stomach contractions and emptying. Gastrin (choice A) stimulates gastric acid secretion, secretin (choice C) regulates pH levels in the duodenum, and cholecystokinin (choice D) stimulates the release of digestive enzymes and bile.
