Membrane consists of lipids and proteins.
Cell membrane function quizlet. The cell membrane has different lipid and protein compositions in distinct types of cells and may have therefore specific names for certain cell types. The cell membrane controls the movement of substances in and out of cells and organelles while protecting the cell from its surrounding. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
Although the basic structure of biological membranes is provided by the lipid bilayer membrane proteins perform most of the specific functions of membranes. A rigid structure that surrounds the cells of plants and most bacteria. What is the function of the cell membrane quizlet.

Its function is to contribute energy and act as a marker for cellular recognition. It maintains the integrity of a cell and controls passage of materials into and out of the cell. Thus we associate the majority of functional properties of cell membranes with the membrane proteins.
Although the sarcolemma is similar to other cell membranes it has other functions that set it apart. The cell membrane separates the material outside the cell extracellular from the material inside the cell intracellular. This thin barrier 8 nm thick controls traffic into and out of the cell.
Take up the quiz below and get to see how much you understood about its structure and how it helps it attain its functions. Sarcolemma in muscle cells. The plasma membrane or the cell membrane provides protection for a cell.
