1. Exchange Lists for Meal Planning was devised by the American Dietetic Association in collaboration with which organization?

Correct answer: B

Rationale: The correct answer is B: the American Diabetes Association. The American Dietetic Association collaborated with the American Diabetes Association to devise the Exchange Lists for Meal Planning. This collaboration aimed to assist individuals, especially those with diabetes, in planning balanced meals. Choices A, C, and D are incorrect as they were not involved in the development of the Exchange Lists.

2. How is the enzyme trypsin activated?

Correct answer: D

Rationale: The correct answer is D: By enterokinase. Trypsin is activated by enterokinase, an enzyme secreted by the small intestine. Enterokinase plays a crucial role in converting trypsinogen into its active form, trypsin. Choices A, B, and C are incorrect because trypsin is specifically activated by enterokinase, not by zymogen, bile, or gastrin.

3. Most fat replacers are made from:

Correct answer: B

Rationale: Most fat replacers are made from carbohydrates. Carbohydrates are utilized to mimic the texture of fats in food products. Proteins (Choice A) are not commonly used as fat replacers and are more often associated with other functions in food. Cholesterol (Choice C) is a type of fat and not used to replace fat in food products. Monoglycerides (Choice D) are sometimes used as emulsifiers or stabilizers in food products but are not the primary source of fat replacers.

4. What are the small, fingerlike projections into the intestinal lumen called?

Correct answer: A

Rationale: The correct answer is A: Villi. Villi are small fingerlike projections in the intestine that increase the surface area for nutrient absorption. Goblets (choice B) are mucus-secreting cells in the intestines. Lacteals (choice C) are lymphatic vessels in the small intestine that absorb dietary fats. Polyps (choice D) are abnormal tissue growths.

5. In addition to active transport, which process is involved in absorbing food in the small intestine?

Correct answer: A

Rationale: The correct answer is pinocytosis. Pinocytosis is a process where cells in the small intestine absorb nutrients by engulfing them. This process is different from phagocytosis, which involves engulfing large particles, and excretion, which is the removal of waste products. Electrochemical diffusion is not directly involved in the absorption of food in the small intestine.
