Question

question 4
which of the following is true during the resting membrane potential?
a a greater concentration of calcium ions is found inside the cell
b sodium ion concentration is greater inside cells
c negatively charged proteins are more concentrated outside the cell
d none of these choices reflect what occurs during the resting membrane potential
e potassium is concentrated primarily inside the cell

Explanation:

During resting membrane potential, potassium (\(K^+\)) is concentrated primarily inside the cell. Sodium (\(Na^+\)) is more concentrated outside. Calcium (\(Ca^{2+}\)) is also more outside. Negatively - charged proteins are more inside.

Answer:

E. Potassium is concentrated primarily inside the cell
