The Plasma Membrane - An Overview, Facts and its Importance

NettetSurface area and thickness of the plasma membrane: Increased surface area increases the rate of diffusion, whereas a thicker membrane reduces it. Distance travelled: The greater the distance that a substance must travel, the slower the rate of diffusion. This places an upper limitation on cell size.

NettetThe fluidity of the plasma membrane is necessary for the activities of certain enzymes and transport molecules within the membrane. Plasma membranes range from 5–10 nm thick. As a comparison, human red blood cells, visible via light microscopy, are approximately 8 µm thick, or approximately 1,000 times thicker than a plasma … NettetThe membrane is about 5 nanometers thick. A nanometer is 10-3 micrometers, so the membrane thickness is about 4000 times smaller than the diameter of the cell. Why does membrane fluidity increase temperature? As temperature increases, so does phospholipid bilayer fluidity. …
