In this article we will discuss about the passive and active transport of substances across plasma membrane. All substances moving from outside to inside a cell, be it from external environment to epithelial cells of the body surface or from interstitial fluid to cell inside the body, must pass through the plasma membrane surrounding the cell. The plasma membrane is [...]
The following points highlight the top five functions of plasma membrane. The functions are: 1. Providing a Selectively Permeable Barrier 2. Transporting Solutes 3. Transporting Macromolecules 4. Responding to External Signals 5. Intercellular Interaction 6. Energy Transduction. Plasma Membrane: Function # 1. Providing a Selectively Permeable Barrier: Plasma membrane prevents the free interchange of materials from one side to the [...]
