Question

ions are unequally distributed across the plasma membrane of all cells. this ion distribution creates an electric potential difference across the membrane. what is the name given to this potential difference?
action potential
resting membrane potential (rmp)
threshold potential
positive membrane potential

Explanation:

• Action potential is a temporary change in membrane potential during nerve impulse transmission, not the resting ion - distribution - based potential.
• Resting membrane potential (RMP) is the electrical potential difference across the plasma membrane of a cell at rest, which is created by the unequal distribution of ions across the membrane.
• Threshold potential is the membrane potential at which an action potential is initiated, not related to the resting ion - distribution - based potential.
• Positive membrane potential is not a standard term for the potential difference due to resting ion distribution.

Answer:

B. Resting membrane potential (RMP)
