Question

Excitation- contraction coupling is the sequence of processes that links the action potential to contraction. threshold period of an action potential. sliding of thin filaments past thick filaments during muscle fiber contraction. refractory period of an action potential. transfer of ACh into the synaptic cleft.

Answer 1

Answer:

The correct answer is - sequence of processes that links the action potential to contraction.

Explanation:

The depolarization of the cardiomyocyte plasma membrane is binded to the calcium ions that release from the sarcoplasmic reticulum to stimulates sarcomeric actomyosin cross-bridge to the formation and the generation of a contractile force, known as Excitation- contraction coupling.
