1.	Which of the following statements about action potential is false?(a) Na^+/K^+ pumps are directly involved in creating the action potential(b) Na^+ and K^+ concentrations are not significantly changed during an action potential(c) This includes both positive and negative feedback loops(d) Only a relatively small number of Na^+ and K^+ actually diffuse across the membraneI have been asked this question in an online interview.My question comes from Gated Ion Channels in division Biosignalling of Biochemistry
Answer» RIGHT answer is (B) Na^+ and K^+ CONCENTRATIONS are not significantly CHANGED during an action potential Explanation: The concentration of K^+ is higher inside and concentration of Na^+ is more OUTSIDE.
