What is Membrane Potential

Question

What is membrane potential?
A) The rate of ATP production and transport by mitochondria.
B) The ability of a membrane to actively transport carbohydrates out of the cytoplasm.
C) The electrical charge difference across the membrane caused by ion movement.
D) The ability of molecules to pass through the nuclear membrane.

Accepted Answer

Membrane potential is the electrical charge difference across the membrane caused by ion movement. This is due to the fact that the cell membrane is selectively permeable and allows only certain ions to move across it, leading to an unequal distribution of charges on either side of the membrane.
