Membrane potential is determined by the:

A. difference in concentration of ions and charged molecules on the two sides of a cell's plasma membrane

B. concentration of cholesterol in a membrane

C. number and type of phospholipids present in a membrane

D. number and types of ion-channel proteins present in the plasma membrane of a cel

A. difference in concentration of ions and charged molecules on the two sides of a cell's plasma membrane

Explanation:

The plasma membrane is a type of selective membrane that plays an important role in regulating the molecules, ions and some other across the membrane. It is made of phospholipid bi layer. The potential difference occurs due to the diffrence between the ions concentration inside and outside of the membrane. The membrane potential plays an important role in the process of membrane polarization, depolarization, and some other conditions.
