Question

what is a function of transverse tubules? multiple choice to transmit action potentials (impulses) into the cell interior to store sodium ions needed to initiate an action potential at the cell surface to store calcium ions needed for activating tropomyosin to connect actin to the myosin filaments

Explanation:

Transverse tubules (T - tubules) are invaginations of the muscle cell membrane. Their main function is to rapidly transmit the action potential from the cell surface deep into the cell interior, triggering muscle contraction. They do not store sodium or calcium ions for the functions described in the other options, nor do they connect actin and myosin filaments.

Answer:

To transmit action potentials (impulses) into the cell interior
