Anionic proteins and phosphates have little influence over the resting membrane potential (RMP) because
A) they are found in roughly equal concentrations across the membrane
B) they are negatively charged, and the rmp relies on positive charges
C) they are bound to cations and thus can't cross the membrane
D) they do not have leak channels and thus can't cross the membrane

Question

Quizplus · Accepted Answer

Anionic proteins and phosphates significantly influence the resting membrane potential (RMP) because they are large, negatively charged molecules that cannot easily cross the cell membrane due to the lack of specific leak channels. This inability to cross the membrane contributes to the negative charge inside the cell relative to the outside, which is a key factor in establishing the RMP.
