Propose a valid reason to explain why is it critical that the K+ channel activation gate responds slightly slower to depolarization than the Na+ channel activation gate.
A. If both gates showed identical response times, movements of Na+ and K+ ions would magnify each other's effects on membrane potential changes, creating dangerously large action potentials. B. The conformational change in one gate is necessary to trigger the activation of the other. C. It is not critical and there would be no change in action potential characteristics if this difference in response time did not exist. D. If both gates showed identical response times, movements of Na+ and K+ ions would cancel out each other's effects on membrane potential changes.
