Question

Quizplus · Accepted Answer

The membrane potential is primarily maintained by the electrochemical gradient of ions across the cell membrane, which results from the differential distribution of ions (such as Na+, K+, Cl-, and Ca2+) between the inside and outside of the cell. This gradient is crucial for various cellular functions, including the generation of action potentials in neurons.
