Introduction

Plasma membrane or cell membrane is a outermost membrane in animal cell. It protect the cell from external injury. It is a selectively membrane. Plasma membrane allows some selective molecules to move in and out the cell. Plasma membrane has Na+K+ pump, which is a ATPase pump which maintain membrane potential across the cell membrane.
