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.

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

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.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
