PPT-The Plasma Membrane Maintaining a Balance

The plasma membrane is a SELECTIVELY PERMEABLE membrane that allows nutrients and wastes to enter and exit the cell Homeostasis maintaining balance in the cell The Plasma Membrane Selective Permeability allows some molecules to pass through and keeps others out. -.

Module 1: Components a nd Architecture o f Cell Membrane Learning objectives: In this module, prime focus is mainly on the plasma membrane, however, majority of the concepts discussed below are also S.J. Singer and Garth L. Nicolson proposed the fluid mosaic model , which is widely used.. The fluid mosaic model of the plasma membrane structure describes the plasma membrane as a fluid combination of phospholipids, cholesterol, proteins, and carbohydrates..
