University. Physiology of Plasma membrane. :. The plasma membrane acts as a thin barrier which separates the intracellular fluid or the cytoplasm from extracellular fluid in which the cell live.. Plasma membranes :. Membranes. cover the surface of every cell and also surround most organelles within cells. They have a number of functions, such as:. keeping all cellular components inside the cell. primarily . of ______.. DNA. Protein. Carbohydrates. Phospholipids. 2. The . phospholipids in the cell membrane are arranged in a bilayer (double layer). How are the phospholipid molecules arranged in this bilayer?. Presented by. Dr . Sanjoy. Deka. PLASMA MEMBRANE OR CELLMEMBRANE. Points to be discussed…. Nature of plasma membrane. Movement of substances across plasma membrane. Diffusion and osmosis. Hypotonic, isotonic and hypertonic solution. The concentration of many of these are affected by pathological processes; they are therefore measured.. They contain disulphide bonds.. Functions of plasma proteins include:. Transport.
