1. Exchange Lists for Meal Planning was devised by the American Dietetic Association in collaboration with which organization?
- A. the American Cancer Society
- B. the American Diabetes Association
- C. the American Heart Association
- D. the Culinary Institute of America
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. What is the mechanism that is essential for the absorption of monosaccharides?
- A. Phosphorylation
- B. Active transport
- C. Passive diffusion
- D. Facilitated diffusion
Correct answer: B
Rationale: Active transport is the mechanism essential for the absorption of monosaccharides in the intestine. This process requires energy to move molecules against their concentration gradient, allowing for the absorption of monosaccharides efficiently. Phosphorylation, the process of adding a phosphate group to a molecule, is not directly involved in the absorption of monosaccharides. Passive diffusion, a process that does not require energy, is not the primary mechanism for absorbing monosaccharides due to their large size. Facilitated diffusion, a type of passive transport that involves carrier proteins, is not the primary mechanism for monosaccharide absorption, as monosaccharides require active transport for efficient absorption.
3. The process of photosynthesis is responsible for the synthesis of:
- A. carbohydrates.
- B. proteins.
- C. fats.
- D. vitamins.
Correct answer: A
Rationale: The correct answer is A: carbohydrates. Photosynthesis is the process by which plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy stored in glucose (a type of carbohydrate). This glucose is used by the organisms for energy production and as a building block for other organic compounds. Choice B, proteins, is incorrect because proteins are synthesized through a different process involving amino acids. Choice C, fats, are not directly synthesized through photosynthesis; they are typically formed from excess carbohydrates. Choice D, vitamins, are organic compounds that are required in small amounts for various physiological functions but are not directly synthesized through photosynthesis.
4. What are the actions involved in the process of digestion?
- A. thermal and chemical.
- B. chemical and segmental.
- C. muscular and chemical.
- D. mechanical and thermal.
Correct answer: C
Rationale: The correct answer is C: 'muscular and chemical.' In the process of digestion, muscular movements help in mixing and propelling food along the digestive tract, while chemical breakdowns involving enzymes and acids break down food into smaller molecules for absorption. Choices A, B, and D are incorrect as thermal, segmental, and mechanical actions are not the primary actions involved in the digestion process.
5. How many kilocalories are provided by 15 grams of protein?
- A. 15
- B. 45
- C. 60
- D. 135
Correct answer: C
Rationale: Protein provides 4 kcal per gram. Therefore, 15 grams of protein will provide 15 grams x 4 kcal/gram = 60 kcal. Choices A, B, and D are incorrect because they do not consider the caloric value of protein correctly.
