Question

Quizplus · Accepted Answer

A protein that is temporarily associated with a biological membrane is a peripheral membrane protein. Peripheral membrane proteins are not embedded in the hydrophobic region of the membrane and can be easily removed from the membrane through changes in pH, salt concentration, or by chelating agents, and they only interact with the membrane temporarily. In contrast, integral membrane proteins such as transmembrane proteins are embedded in the hydrophobic region of the membrane and cannot be removed from the membrane without disrupting its structure.
