Moreover, this network has been shown to exist in other cells as well. In the present review, through taking a view of plasma membrane from inside the cell (see Fig. 2), the structure-function correlation of the red cell membrane skeleton and its regulations are summarized....

Structure of the Plasma Membrane Other components of the plasma membrane The plasma membrane also contains cholesterol, proteins, and carbohydrates. Some proteins called receptors transmit signals to the inside of the cell. Some proteins serve as support structures for the membrane. Transport proteins m...

The Plasma/Cell Membrane Objective Recognize the importance of semi-permeable membranes in regulating diffusion and maintaining homeostasis. The Cell Membrane The “cell membrane” is also known as “the plasma membrane.” To survive, ALL living things must maintain a balance regardless of internal an...

The plasma membrane is a complex structure; various molecules pack tightly together to form a semi-impermeable barrier for the cytoplasm, nucleus, and intercellular organelles53. Nevertheless, under certain assumptions as described below, it is appropriate to model this complex and heterogeneous surface...
