Answer:

Explanation:
The excitation-contraction coupling process is the process by which the electrical activation of muscles (the depolarization of the action potential) leads to the activation of contraction.
An action potential in the skeletal muscles or muscle excitation leads to Ca release from the sarcoplasmic reticulum via calcium channel protein. Released Ca regulates the contraction of the muscle.
William Martin and Michael Russell noted that hot iron sulfide rising from the below the ocean floor combined with the cooler ocean water to form to me like structures made of many compartments and that biological molecules combined in the compartments of these two minutes the walls of the compartments were thought to act is the first cell membranes.
