CELL MEMBRANE

The ____________________ ____________________ , also called the ____________________ ____________________ , is found in all cells and ____________________ the interior of the cell from the outside environment . The cell membrane consists of a ____________________ bilayer that is ____________________ . The ____________________ ____________________ regulates the ____________________ of ____________________ entering and exiting the cell .

The plasma membrane , or the ____________________ ____________________ , provides ____________________ for a ____________________ . It also provides a fixed environment inside the cell , and that membrane has several ____________________ ____________________ . One is to ____________________ ____________________ into the cell and also to ____________________ ____________________ ____________________ out of the cell .

Another is that the ____________________ of the cell , which would be the plasma membrane , will have ____________________ on it which interact with other ____________________ . Those proteins can be ____________________ , meaning there's a sugar and a protein moiety , or they could be ____________________ ____________________ , meaning that there's a fat and a protein .

And those ____________________ which stick outside of the ____________________ membrane will allow for one ____________________ to interact with another cell . The ____________________ ____________________ also provides some ____________________ support for a cell . And there are different types of plasma ____________________ in different types of cells , and the plasma membrane has in it in general a lot of ____________________ as its ____________________ component .
