Summary Introduction

To write:

Concentration gradients for sodium and potassium across the plasma membrane. Reason for these concentration gradients.

Introduction:

The term concentration gradient means the process of movement of solutes or particles through a solution from the area of higher concentration to the area of lower concentration. Such areas are generally parted by a membrane, which can be permeable, semi-permeable, or non-permeable. The movement of particles is through, passive transport, active transport, or facilitative diffusion.
