Question

True or False

1. Skeletal muscle may also be classified as striated and voluntary.

2. Type I skeletal muscle fibers are well-designed for using lactic acid as a substrate for aerobic metabolism.

3. An action potential elicited in one skeletal muscle fiber results in action potentials in all fibers of the muscle.

Answer 1

1. Answer:  TRUE

Explanation: Skeletal muscle is meant for contraction of the muscle. These functional units of contraction are done by striated muscle. There are various types of muscle. Voluntary action is controlled by skeletal muscle, where skeletal muscle gives controlled movement to various tissue.

2. Answer: FALSE

Explanation: Aerobic pathway of metabolism requires glucose and oxygen as the source of substrate.

3. Answer:  FALSE

Explanation: Action potential in skeletal muscle reflects the only voluntary region of the muscle tissue. It won't affect other types of muscle fiber action. A separate response is reflected in other muscle fiber tissue.
