Question

The function of transverse tubules is to a. store Ca2 ions inside the muscle fiber. b. rapidly move action potentials to the interior of the muscle fiber. c. ensure a supply of glycogen throughout the muscle sarcoplasm. d. conduct ATP molecules out of the mitochondria throughout the sarcoplasm.

Answer 1

The function of transverse tubules is to rapidly move action potentials to the interior of the muscle fiber.

Step-by-step explanation:

The function of the transverse tubules is to bring the action potential of the sarcolemmal cell membrane to the sarcomeres, where the contractile machinery of the muscle fiber is organized.
