The cell membrane (plasma membrane) is a thin semi-permeable membrane that surrounds thecytoplasmof acell. Its function is to protect the integrity of the interior of the cell by allowing certain substances into the cell while keeping other substances out. It also serves as a base of attachmen...
The Cell Membrane Cellsare the basic building block of all living things. Someliving things are composed ofonly a single cell, while others are composed of many cells. What cells do depends on their location in an organism. Cells can work together to serve a particular function in the form...

Cell Membrane | Function, Structure & Purpose from Chapter 3 / Lesson 6 1.3M In this lesson, you will learn about the parts of the cell membrane and the cell membrane functions. In addition, you will explore the role proteins in the cell membrane. Related...
In order to achieve this function, cell membranes contain embedded membrane proteins that play different roles. Several of families of membrane proteins have been identified, such as (1) channels and pores which control the exchange of ions and water between the inside and outside of the cell ...

A new aspect of cell membrane structure is presented, based on the dynamic clustering of sphingolipids and cholesterol to form rafts that move within the fluid bilayer. It is proposed that these rafts function as platforms for the attachment of proteins when membranes are moved around inside the...
Therefore, the collection of lipids and proteins that make up a cellular membrane relies on natural biophysical properties to form and function. In living cells, however, many proteins are not free to move. They are often anchored in place within the membrane by tethers to proteins outside the...
