Propose a Valid Reason to Explain Why Is It Critical

question 44

Multiple Choice

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 cancel out each other's effects on membrane potential changes.
• B)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.
• 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)The conformational change in one gate is necessary to trigger the activation of the other.
