Question

During repolarisation of a neuron, select the ion which moves outside from intracellular fluid of axon by voltage gated channels. a)K^ +
b) Na^ +
c) Ca ^ (+ 2)
d)Cl^ -​

Answer 1

Repolarization typically results from the movement of positively charged K+ ions out of the cell. The repolarization phase of an action potential initially results in hyperpolarization, attainment of a membrane potential, termed the afterhyperpolarization, that is more negative than the resting potential.
