Question

During the propagation of a nerve impulse, the Q action potential results from the movement of:

Answer 1

Na⁺ ions from extracellular fluid to intracellular fluid because during propagation of nerve impulse, Na⁺ entersinside so +ve change is formed inside the membrane. K⁺ ions come out.

Answer 2

Answer:

Inflow of Na+

Explanation:

when stimulated,voltage gated Na+ channel open which causes a rapid temporary inflow of Na+ developing a net +vet charge on inner side of mem.
