Question 1

Which of the following best describes the role of insulin in carbohydrate metabolism?

Accepted Answer

Insulin facilitates glucose uptake into cells and promotes glycogen synthesis, reducing blood glucose levels

Answer

Insulin is secreted by the pancreas in response to elevated blood glucose. It facilitates glucose uptake into muscle and fat cells, promotes glycogen synthesis, and signals energy storage.

Question 2

Complete proteins differ from incomplete proteins in that they:

Accepted Answer

Provide all nine essential amino acids in adequate quantities

Answer

Complete proteins contain all nine essential amino acids (EAAs) — those the body cannot synthesize and must obtain from food — in sufficient quantities to support protein synthesis.

Question 3

The Thermic Effect of Food (TEF) refers to:

Accepted Answer

The increase in metabolic rate following food consumption to digest, absorb, and metabolize nutrients

Answer

TEF is the energy expenditure required to digest, absorb, and process food. Protein has the highest TEF (20–30%), followed by carbohydrates (5–10%), then fat (0–3%).

Question 4

Which type of dietary fat is associated with increased LDL cholesterol and cardiovascular risk when consumed in excess?

Accepted Answer

Saturated fats

Answer

Saturated fats (found in fatty meats, butter, full-fat dairy, coconut oil) are associated with elevated LDL cholesterol, which increases cardiovascular disease risk when consumed in excess.

Question 5

Glycogen is primarily stored in which two locations in the human body?

Accepted Answer

Liver and skeletal muscle

Answer

Glycogen is stored in the liver (regulates blood glucose, ~100 g capacity) and skeletal muscle (fuels muscle contraction, ~300–500 g capacity in trained individuals).
