Drawing Of A Cell Membrane

Drawing Of A Cell Membrane - (a) the plasma membrane of a cell is a bilayer of glycerophospholipid molecules. All cells have a cell membrane that separates the inside and the outside of the cell, and controls what goes in and comes out. Explain the major features and. Describe how molecules cross the cell membrane based on their properties and concentration gradients. Web according to the fluid mosaic model, the plasma membrane is a mosaic of components—primarily, phospholipids, cholesterol, and proteins—that move freely and fluidly in the plane of the membrane. In other words, a diagram of the membrane (like the one below) is just a snapshot of a dynamic process in which phospholipids and proteins.
