Question 1

Which lipoprotein is primarily responsible for transporting dietary fat from the intestines to peripheral tissues?

Accepted Answer

Chylomicron

Answer

Chylomicrons are assembled in intestinal enterocytes and carry dietary triglycerides through the lymphatic system to peripheral tissues.

Question 2

What is the primary role of glucagon in macronutrient metabolism?

Accepted Answer

Raises blood glucose by stimulating glycogenolysis and gluconeogenesis

Answer

Glucagon signals the liver to break down glycogen and produce new glucose, counteracting the effects of insulin during fasting states.

Question 3

Which amino acid is considered rate-limiting for muscle protein synthesis?

Accepted Answer

Leucine

Answer

Leucine acts as a key anabolic signal that directly activates the mTORC1 pathway to initiate muscle protein synthesis.

Question 4

The thermic effect of protein is approximately what percentage of its caloric value?

Accepted Answer

20–30%

Answer

Protein requires 20–30% of its own calories to be digested, absorbed, and metabolized, giving it the highest thermic effect of the three macronutrients.

Question 5

What is the primary storage form of carbohydrates in the human body?

Accepted Answer

Glycogen

Answer

Glycogen is a branched polymer of glucose stored in the liver (~100 g) and skeletal muscle (~400 g) for rapid energy release.
