Summary Introduction

To review:

The effect of poison that blocks the K⁺ (potassium ion) leak channels on the resting membrane potential of skeletal muscle fibers. Also, the rationale behind the process.

Introduction:

Resting membrane potential generation depends on two types of ions, namely sodium and potassium ions. When these ions are charged, they cannot pass the hydrophobic plasma membrane. Their movement is facilitated by some membrane proteins known as protein channels. The leak channels are always open and continuously allow the flow of gradients.
