Document Summary
^structure of a plasma membrane: plasma membrane- thin, blue film around the cell. It forms the outer bond boundary of the cell. Serves as a selective barrier- what gets in and what gets out. Cancer cells cannot communicate and tell it to stop dividing. It is a lipid bilayer which consists of cholesterol, glycoproteins, etc. Peripheral proteins are on the outside of the lipid bilayer. They are attached to the inner or outer. They support the plasma membrane and contain enzymes that start the chemical reactions within the cell. Transporters decides what goes through the plasma membrane and helps it do so. Glycoproteins- membrane proteins that have a carbohydrate attached to it. It is a carbohydrate attached to a protein. Glycocaylics- all those glycoproteins together that make up a sugary protein on the membrane. It serves as a lubricant, acts as a cell identifier, and helps cells bind together. can be permeable or impermeable.
