1. A food choice equivalent to one serving from the Grains group of MyPlate is:

Correct answer: A

Rationale: One slice of bread is a standard serving from the Grains group in MyPlate. This choice aligns with the recommended portion size for grains. Choices B, C, and D are excessive portions that do not represent a single serving according to MyPlate guidelines. 2 cups of rice, 3 cups of spaghetti, and 4 oz of ready-to-eat cereal exceed the standard serving size for grains and would provide more than one serving from this food group.

2. What substance activates pepsinogen to pepsin?

Correct answer: D

Rationale: The correct answer is D: Hydrochloric acid. Hydrochloric acid in the stomach plays a crucial role in converting pepsinogen into its active form, pepsin, which is necessary for digesting proteins. Bile (Choice A) is involved in the emulsification of fats, not in the activation of pepsinogen. Gastrin (Choice B) is a hormone that stimulates the secretion of gastric acid but does not directly activate pepsinogen. Secretin (Choice C) is a hormone that regulates the pH of the duodenum but is not responsible for the activation of pepsinogen.

3. Which tissue has the highest rate of protein turnover?

Correct answer: B

Rationale: The correct answer is B: Intestinal mucosa. The intestinal mucosa has the highest rate of protein turnover due to its rapid cell renewal. The skin, muscle, and adipose tissue do not exhibit protein turnover rates as high as the intestinal mucosa. Skin cells turnover relatively slower compared to the rapid renewal of intestinal mucosa cells. Muscles have a moderate rate of protein turnover, while adipose tissue has a lower turnover rate compared to the other tissues mentioned.

4. Which nutrient group provides the primary source of energy for the body?

Correct answer: A

Rationale: Carbohydrates are the body's primary source of energy. When carbohydrates are consumed, they are broken down into glucose, which is used by the body's cells for energy production. Fats and proteins are also essential nutrients, but carbohydrates are the preferred energy source for the body due to their quick conversion into fuel. Vitamins are not a direct source of energy but play crucial roles in various bodily functions.

5. To prevent symptoms of fatigue, dehydration, and energy loss, what is the daily recommended minimum intake of carbohydrates?

Correct answer: A

Rationale: The correct answer is A: 130 g. The recommended minimum intake of carbohydrates to prevent fatigue, dehydration, and energy loss is 130 grams per day. Consuming an adequate amount of carbohydrates provides the body with energy and helps prevent symptoms associated with insufficient carbohydrate intake. Choices B, C, and D are incorrect as they suggest higher amounts of carbohydrate intake, which may not necessarily align with the recommended daily minimum intake for preventing symptoms of fatigue, dehydration, and energy loss.
