If the charge difference across the plasma membrane is decreased,
A) the potential difference across the plasma membrane does not change.
B) the membrane potential is more positive.
C) the change is called hyperpolarization.
D) negative proteins can leave the cell.
E) the membrane potential is more negative.

Question

Quizplus · Accepted Answer

When the charge difference across the plasma membrane decreases, it means that the inside of the cell becomes less negative relative to the outside. This results in the membrane potential becoming more positive. Hyperpolarization refers to an increase in the membrane potential, making the inside of the cell more negative, which is not the case here. Negative proteins typically cannot leave the cell due to their size and the selective permeability of the plasma membrane.
