Chapter 6, Problem 30RA

Summary Introduction

To review:

The contribution of the Na+/K+ pump to the resting membrane potential and the permeability of plasma membrane toward sodium and potassium ions.

Introduction:

The polar molecules across the plasma membrane do not cross the membrane by simple diffusion transport. They are transported through facilitated diffusion or by active transport. The facilitated diffusion occurs through the carrier proteins or channels that are present in the membrane. They show specificity or constancy toward the molecules that present across the membrane.
