Expert Solution
Step 1: Understanding the resting membrane potential of a cell
The resting membrane potential of a cell is largely determined by the concentrations of various ions inside and outside the cell, and the permeability of the cell membrane to these ions. Ion channels and transport mechanisms play a crucial role in maintaining these concentrations and permeabilities.
