which determines the size of the resting membrane potential?

Question

A) the inital size of the concentration gradient established by the sodium/potassium pump
B) the size of the cell
C) the number of voltage grated K+ channels
D) the number of voltage grated Na+ channels

Answer 1

Answer = A

A larger cell (answer B) can hold more charged particles, but a small cell with 5 charged particles will have the same potential as a large cell with 5 charged particles!

(C) and (D) relate to how quickly the cell can re-creat the resting membrane potential once, say, an action potential has passed through the nerve.

Answer 2

The Na+/ok+ pump is electrogenic. It pumps 2K+ into the cellular for each 3Na+ out of the cellular growing to be a unfavourable interior cost and positive outdoors. It subsequently maintains a extreme intracellullar ok+ concentration and extreme Na+ extracellular concentration. Proteins interior the cellular can carry a unfavourable cost and could also influence the membrane capacity.
