Question

Consider a typical cell at its resting membrane potential (rest V_m). The membrane temporarily becomes more permeable to Na+. Ena = +55mV, resting V_m = 60m V Would you expect the sodium equilibrium potential (Ex) to change? a. No b. Yes, become more negative c. Yes, become more positive Consider a typical cell at its resting membrane potential (rest V_m). The membrane temporarily becomes more permeable to Na+. Ena = +55mV, resting V_m = -60m V Would you expect the membrane potential (V_m) to change, if so how? a. No. b. Yes, become more negative. c. Yes, become less positive d. Yes, become less negative Consider a typical cell at its resting membrane potential (rest V_m). The membrane temporarily becomes more permeable to Na+. Ena = +55mV, resting V_m = -60m V Would you expect the membrane to depolarize, repolarize, hyperpolarize, or no change? a. No change b. De polarize c. Hyperpolarize d. Repolarize
