Question 3

Correct Answer:

Verified

While Cl^- influx is associated with hyperpolarization during IPSP occurrence, it doesn't contribute significantly to the action potential. The influx of Na⁺ causes the rising phase of the action potential as a positive hyperpolarization, while the efflux of K⁺ is associated with the falling phase of the action potential as depolarization and then negative hyperpolarization to and beyond the resting membrane potential voltage value.
