Question

Which statement best describes fat and carbohydrate metabolism in the fasting state?

A

Muscle proteins are converted to glucose, while glycogen remains in the liver, unmetabolized. Adipose tissue releases fatty acids.

B

Muscle proteins and glycogen are converted to fatty acids; adipose tissue converts glycerol into glucose.

C

There is no carbohydrate metabolism in the fasting state; instead adipose tissue releases fatty acids and ketone bodies as sources of energy.

D

Muscle proteins and glycogen are converted to glucose; adipose tissue releases fatty acids into the blood.

Explanation / Answer

D is the correct option...

Muscle proteins and glycogen are converted to glucose; adipose tissue releases fatty acids into the blood.

In early fasting stage glycogen is converted to glucose(via glycogenolysis) and in late fasting stage, muscle proteins are converted to glucose (via gluconeogenesis)
