Distinguish between the structure and function of integral membrane proteins and peripheral
membrane proteins.
What will be an ideal response?
Integral proteins are suspended individually in the phospholipid bilayer, while peripheral proteins are attached to integral proteins or membrane lipids on the cytoplasmic side of the membranes (mostly). Transport, receptor recognition, and cell adhesion proteins that give membranes their specific function are integral membrane proteins. Peripheral membrane proteins are parts of the cytoskeleton or proteins that link the cytoskeleton together. As such, peripheral proteins are anchored or held in place so that the protein receptors face body cavities, surfaces or tubes. The differences between and among the orientation of both types of proteins result in membranes being asymmetric.
