Chapter 11, Problem 2CYU

Summary Introduction

To review:

The overall effect on action potential when a drug inhibits the K⁺ (potassium ions) channels.

Introduction:

The sequential depolarization and repolarization of a cell contribute toward an action potential, which is primarily governed by two voltage-gated channels, namely, K⁺ channels/potassium ion channels and Na⁺ channels/sodium ion channels. The opening and closing of these channels determine the precise state of cellular excitability.
