Figure 1: Transport proteins in the cell membrane A plasma membrane is permeable to specific molecules that a cell needs. Transport proteins in the cell membrane allow for selective passage of specific molecules from the external environment. Each transport protein is specific to a certian molecule...

Integral membrane proteins are are embedded within the cell membrane and project into the cell or the external environment. An integral membrane protein that spans the entire cell membrane, from the outer surface of the cell to the inner surface of the cell, is called a transmembrane protein. ...
Deep in your cells is an…envelope! Learn what the nuclear membrane -- also called the nuclear envelope -- is, what it is made of and what it does...
Cells provide structure and support to the body of an organism. The cell interior is organised into different individual organelles surrounded by a separate membrane. The nucleus (major organelle) holds genetic information necessary for reproduction and cell growth. Every cell has one nucleus and memb...
When I took biology I was totally fascinated by the plasma membrane. It really is integral to the cells functioning because of the way it allows some things, but not others, to pass through the membrane. There are also membranes inside the cell. In fact, the compartmentalization inside the ...
Cell Wall in Plant Cells Like plant cells, animal cells have a cell membrane. This is an important barrier that separates the interior parts of the cell from the external environment while also regulating the movement of molecules/substances in and out of the cell. ...
