Detailed explanation-1: -Peripheral membrane proteins, or extrinsic membrane proteins, are membrane proteins that adhere only temporarily to the biological membrane with which they are associated. These proteins attach to integral membrane proteins, or penetrate the peripheral regions of the lipid bilayer.
Detailed explanation-2: -Peripheral proteins are present on the surface of the plasma membrane. They play a role in support, communication, enzymes, and molecule transfer in the cell.
Detailed explanation-3: -Peripheral proteins are attached to the surface of the bimolecular lipid layer, probably by electrostatic interactions, whereas integral proteins are integrated into the lipid bilayer in whole or part (Fig. 5.3A).
Detailed explanation-4: -Peripheral membrane proteins (PMPs) are a class of membrane proteins that attach to the lipid bilayer, acting on the lipid-water interface, in contrast to transmembrane proteins, which are fully embedded in the cell membrane.
Detailed explanation-5: -Only transmembrane proteins can function on both sides of the bilayer or transport molecules across it. Cell-surface receptors are transmembrane proteins that bind signal molecules in the extracellular space and generate different intracellular signals on the opposite side of the plasma membrane.
