Question

the ______ is the difference in electrical charge inside and outside the cell.
transporters
membrane potential
action potential
ion channels

Explanation:

Membrane potential is defined as the electrical potential difference across the cell membrane, between the inside and outside of the cell. Transporters are proteins for moving substances across the membrane, action potential is a brief change in membrane potential, and ion - channels are proteins that allow ions to pass through the membrane.

Answer:

B. membrane potential
