Question

which of the following statement(s) is/are correct regarding the resting membrane potential? select all that apply the membrane potential is a voltage, which is potential energy resulting from the separation of oppositely charged particles. in their resting state, the plasma membranes of all body cells exhibit a resting membrane potential. the charge separation of the resting membrane potential exists only at the membrane; the cell interior is electrically neutral. the minus sign of the resting membrane potential indicates that the outside of the cell is negative compared to its inside.

Explanation:

1. For the first statement: Membrane potential is a voltage (potential energy) from separated oppositely - charged particles (ions across the membrane), so this is correct.
2. For the second statement: All body cells (except maybe some non - excitable ones in a strict sense, but generally) have a resting membrane potential as the plasma membrane is selectively permeable to ions, so this is correct.
3. For the third statement: The charge separation in resting membrane potential is at the membrane; the cell's interior (away from the membrane) and exterior (away from the membrane) are electrically neutral, so this is correct.
4. For the fourth statement: The minus sign of resting membrane potential indicates the inside of the cell is negative compared to the outside, not the other way around, so this is incorrect.

Answer:

• The membrane potential is a voltage, which is potential energy resulting from the separation of oppositely charged particles.
• In their resting state, the plasma membranes of all body cells exhibit a resting membrane potential.
• The charge separation of the resting membrane potential exists only at the membrane; the cell interior is electrically neutral.
