Top 3 Theories of Plasma Membrane

The following points highlight the top three theories of plasma membrane. The theories are: 1. Lamellar Theory 2. Unit Membrane Theory 3. Micellar Theory. 1. Lamellar Theory: "Sandwitch model" proposed by Danielli and Davson (1935), the plasma membrane exhibit trilaminar structure i.e., a lipid layer is bounded by protein layer on both the sides. In this model, proteins are usually [...]

Physiological Functions of Plasma Membrane

The following points highlight the five important physiological functions of plasma membrane. The functions are: 1. Permeability 2. Osmosis 3. Diffusion or Passive Transport 4. Active Transport 5. Endocytosis and Exocytosis. Physiological Function # 1. Permeability: The plasma membrane is a thin, elastic membrane around the cell which usually allows the movement of small ions and molecules of various substances [...]
