Chapter 5.1, Problem 1CYL
Summary Introduction
To describe:
The components, structure, and functions of cell membranes.
Introduction:
Cell membrane surrounds the cells and defines its shape. It is made-up of lipid and proteins, and serves as a barrier by providing permeability to the small molecules, and it also contain signaling and transport system of cells.
