Which of the following is true during the resting membrane potential?

A) Sodium ion concentration is greater inside cells.
B) Negatively charged proteins are more concentrated outside the cell.
C) A greater concentration of calcium ions is found inside the cell.
D) Potassium is concentrated primarily inside the cell.
E) None of these choices reflect what occurs during the resting membrane potential.

Resting Membrane Potential

The voltage difference across the cell membrane when the cell is in an unstimulated, resting state, crucial for the function of nerve and muscle cells.

Sodium Ion

A positively charged ion (Na+) essential for various physiological functions, including nerve impulse transmission and fluid balance in the body.

Calcium Ions

Positively charged calcium atoms (Ca2+) that play vital roles in various biological processes, including muscle contraction, neurotransmission, and blood clotting.
