Which lipoprotein is primarily responsible for transporting dietary fat from the intestines to peripheral tissues?
Answer: Chylomicron
Chylomicrons are assembled in intestinal enterocytes and carry dietary triglycerides through the lymphatic system to peripheral tissues.
What is the primary role of glucagon in macronutrient metabolism?
Answer: Raises blood glucose by stimulating glycogenolysis and gluconeogenesis
Glucagon signals the liver to break down glycogen and produce new glucose, counteracting the effects of insulin during fasting states.
Which amino acid is considered rate-limiting for muscle protein synthesis?
Answer: Leucine
Leucine acts as a key anabolic signal that directly activates the mTORC1 pathway to initiate muscle protein synthesis.
The thermic effect of protein is approximately what percentage of its caloric value?
Answer: 20–30%
Protein requires 20–30% of its own calories to be digested, absorbed, and metabolized, giving it the highest thermic effect of the three macronutrients.
What is the primary storage form of carbohydrates in the human body?
Answer: Glycogen
Glycogen is a branched polymer of glucose stored in the liver (~100 g) and skeletal muscle (~400 g) for rapid energy release.
Which fatty acid classification describes fats with two or more double bonds in their carbon chain?
Answer: Polyunsaturated
Polyunsaturated fatty acids (PUFAs) contain multiple carbon-carbon double bonds, making them liquid at room temperature and essential dietary nutrients.
