Membrane potential is determined by the:

Question

Quizplus · Accepted Answer

Membrane potential is determined by the difference in concentration of ions and charged molecules on the two sides of a cell's plasma membrane. This concentration gradient creates an electrical potential across the membrane, which can be measured as a voltage. The number and types of ion-channel proteins present in the plasma membrane can affect the movement of ions across the membrane, but they do not determine the membrane potential itself. The number and type of phospholipids present in a membrane and the concentration of cholesterol in a membrane may affect the physical properties of the membrane, but they do not directly determine the membrane potential.
