1. Which of the following is the least likely reason that osteoporosis is more prevalent in women?

Correct answer: D

Rationale: The correct answer is D. Contrary to the statement, bone loss begins earlier in women, particularly after menopause, due to the decrease in estrogen levels. This drop in estrogen accelerates bone loss, contributing to the higher prevalence of osteoporosis in women. Choices A, B, and C are more likely reasons for the increased prevalence of osteoporosis in women. Women generally have smaller bodies, lower bone mass compared to men, and may consume less calcium, all of which are significant factors contributing to the higher incidence of osteoporosis in women.

2. The most energy-rich nutrient is:

Correct answer: B

Rationale: Fat provides 9 kcal per gram, making it the most energy-rich nutrient compared to carbohydrates and proteins, which provide 4 kcal per gram.

3. Is it a good idea for an athlete to eliminate all fat from his diet in order to stay lean?

Correct answer: B

Rationale: Fat is an essential energy source during prolonged exercise, so eliminating it entirely from the diet is not advisable for athletes.

4. What is the digestive action of lipase?

Correct answer: C

Rationale: Lipase is an enzyme that specifically breaks down lipids (fats) during the process of digestion, converting them into fatty acids and glycerol. This is why option C is the correct answer. Although option D is partially correct, it's less specific than option C. Lipase does not break down carbohydrates or proteins, so options A and B are incorrect.

5. Which hormone is produced in fat tissue and helps regulate body fat by suppressing appetite?

Correct answer: C

Rationale: The correct answer is C, leptin. Leptin is a hormone produced by fat cells that helps regulate energy balance by suppressing hunger, thus aiding in the regulation of body fat. Glucagon (choice A) is a hormone that raises blood glucose levels, ghrelin (choice B) stimulates appetite, and insulin (choice D) regulates blood sugar levels and promotes glucose uptake.
