What are the main factors that maintain a p8gx)j4sv*q d neuron’s resti/.e-sjh 2j(mzl/u xmdng potential?
A. Sodium ions is Diffuse out ; Potassium ions is Pumped in
B. Sodium ions is Pumped in ; Potassium ions is Pumped out
C. Sodium ions is Pumped out ; Potassium ions is Pumped in
D. Sodium ions is Diffuse in ; Potassium ions is Pumped out
参考答案: C
本题详细解析:
Explanation: Choices A and D are incorrect as the main movement of ions that contributes to the resting potential is done by the $Na^+\,–\,K^+$ pump which is an example of active transport (as opposed to diffusion, which is passive transport). Choice B is incorrect as sodium ions are pumped out of the neuron, and potassium ions are pumped in, which creates the resting potential.
