WebStructure of the Cell Membrane. A cell’s plasma membrane defines the boundary of the cell and determines the nature of its contact with the environment. Cells exclude some substances, take in others, and excrete still others, all in controlled quantities. Plasma membranes enclose the borders of cells, but rather than being a static bag, they ... WebRefer to figure 5.7 in your textbook. Then, on the diagram shown at right, label whether each protein (a-f) is a “peripheral” or “integral” membrane protein. Are any of these proteins “transmembrane” proteins? 6. In 1972 two biologists proposed the “fluid mosaic model” to describe the structure of cell membranes.
WebAll cells share four key components: The plasma membrane is an outer covering that separates the cell’s interior from its surrounding environment. Cytoplasm consists of the jelly-like cytosol inside the cell, plus the cellular structures suspended in it.
