Cell membrane structure and function quizlet. The cell membrane is a biological membrane that separates the interior of all cells from the outside environment which protects the cell from its environment. This organelle functions in cellular respiration. The membrane is composed of a phospholipid bilayer arranged back-to-back.

Regulate the exchange of substances. This membrane separates the fluid outside the cell called extracellular fluid ECF and the fluid inside the cell called intracellular fluid ICF. The cell membrane is a double layer of phospholipid.

Functions of the cell membrane. The membrane is also covered in places with cholesterol molecules and. The organelle functions to package and deliver proteins.

It maintains the integrity of a cell and controls passage of materials into and out of the cell. All materials within a cell must have access to the cell membrane the cells boundary for the needed exchange. The cell membrane consists of a lipid bilayer including cholesterols that sit between phospholipids to maintain their fluidity at various temperatures.

The cell membrane is also known as plasma membrane or plasmalemma. Silica Produced by the cell it protectssupports. Once it infects a susceptible cell however a virus can direct the cell machinery to produce more viruses.
