The charge difference across a membrane produces the membrane potential.

Question

Quizplus · Accepted Answer

Membrane potential refers to the difference in electric potential between the inside and outside of a cell membrane, which arises due to the uneven distribution of ions across the membrane. This charge difference is generated through the active transport of ions by membrane proteins, which creates an electrochemical gradient. Therefore, the charge difference across a membrane is responsible for producing the membrane potential.
