Question 1

Which fatty acid classification describes fats with two or more double bonds in their carbon chain?

Accepted Answer

Polyunsaturated fatty acids

Answer

Polyunsaturated fatty acids (PUFAs) contain two or more carbon-carbon double bonds, making them liquid at room temperature and prone to oxidation.

Question 2

A client following a ketogenic diet is in nutritional ketosis. Which ketone body is produced in the greatest quantity?

Accepted Answer

Beta-hydroxybutyrate

Answer

Beta-hydroxybutyrate (BHB) is the most abundant ketone in the blood during nutritional ketosis, comprising roughly 70-75% of circulating ketones.

Question 3

The glycemic index of a food is measured relative to which reference food?

Accepted Answer

Glucose

Answer

Glycemic index is defined relative to pure glucose (GI = 100), though white bread is sometimes used as an alternative reference in some systems.

Question 4

Which enzyme is responsible for the rate-limiting step in fatty acid synthesis?

Accepted Answer

Acetyl-CoA carboxylase (ACC)

Answer

Acetyl-CoA carboxylase (ACC) catalyzes the conversion of acetyl-CoA to malonyl-CoA, which is the committed and rate-limiting step in de novo lipogenesis.

Question 5

When coaching an athlete for muscle gain, what approximate protein distribution per meal optimizes muscle protein synthesis across the day?

Accepted Answer

Distributing 30-40g of protein across 4-5 meals evenly

Answer

Evenly distributing 30-40g of high-quality protein across multiple meals maximizes the total 24-hour MPS response compared to skewed distribution.
