In the Hodgkin-Huxley explanation of the action potential, activation gates A) Are on ly on Na⁺ channels B) Are only on K⁺ channels C) Are on both Na⁺ and K⁺ channels and have similar kinetics D) Are on both Na⁺ and K⁺ channels but Na+ kinetics are slower E) Are on both Na⁺ and K⁺channels but Na+ kinetics are faster

Question

Quizplus · Accepted Answer

Activation gates are present on both sodium (Na+) and potassium (K+) channels, but the kinetics of Na+ channel activation are faster than those of K+ channels. This difference in kinetics is crucial for the sequential phases of the action potential.
