MUSCLE CONTRACTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The impulse/membrane potential caused by the ion channels affects what in the muscle cell?
A
The impulse releases more ACh
B
The impulse releases more calcium
C
The impulse releases ATP
D
The impulses releases ADP
Explanation: 

Detailed explanation-1: -Membrane potential is a potential gradient that forces ions to passively move in one direction: positive ions are attracted by the ‘negative’ side of the membrane and negative ions by the ‘positive’ one.

Detailed explanation-2: -The principal ions involved in an action potential are sodium and potassium cations; sodium ions enter the cell, and potassium ions leave, restoring equilibrium.
