C)fatty acids.
D)glycogen.

Question

Quizplus · Accepted Answer

During rest, skeletal muscles obtain most of their energy from the aerobic respiration of fatty acids. This is because during rest, the body does not require a large amount of energy, and therefore, the metabolism of fatty acids provides enough energy to meet the body’s needs. Additionally, the breakdown of glycogen and glucose is not preferred since they are stored carbohydrates and the body wants to preserve them for times of higher demand. Protein is not a preferred source of energy for the body to use during rest.
