Sav [38]

Answer: 1. The resting membrane potential would become less negative (more positive).

Explanation:

Resting membrane potential is a voltage carried by a resting (non-signaling) neuron, or called as resting potential, across its membrane.  The resting potential is determined by ion concentration gradients across the membrane, and the permeability of the membrane to each ion form.  

In a resting brain, there are gradients of concentration across the Na+ and K+ membranes. Forces shift their gradients down through channels, resulting in a separation of charges that provides the potential for rest. The membrane is much more permeable to K+ than to Na+, so the resting potential is similar to K+'s potential for equilibrium.

Hence, the correct option is 1. The resting membrane potential would become less negative (more positive).
