Question

the resting cell membrane is more permeable to which ion?
multiple choice
sodium
magnesium
potassium
calcium

Explanation:

At resting state, the cell membrane has more potassium leak channels than sodium leak channels. Potassium ions (\(K^+\)) can diffuse out of the cell more easily than other ions like sodium (\(Na^+\)), magnesium (\(Mg^{2+}\)), or calcium (\(Ca^{2+}\)) due to these channel properties. This contributes to the resting membrane potential.

Answer:

Potassium
