Question

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

Explanation:

• Threshold potential is the critical level to which a membrane potential must be depolarized to initiate an action potential.
• Positive membrane potential is a general description and not the specific term for the potential due to unequal ion distribution.
• Action potential is a rapid rise and fall in membrane potential.
• Resting membrane potential (RMP) is the electrical potential difference across the plasma membrane when the cell is at rest, which is caused by the unequal distribution of ions.

Answer:

Resting membrane potential (RMP)
