Membrane proteins, like membrane lipids, can move laterally by exchanging positions with other membrane components.Which type of membrane protein is expected to be the least mobile, based on their function?

Question

Quizplus · Accepted Answer

Anchors are responsible for anchoring the membrane to the cytoskeleton or extracellular matrix and therefore are expected to be the least mobile, as their function requires them to remain fixed in place. Channels, receptors, and enzymes are all involved in transport, signaling, or catalysis and may need to move to interact with other molecules or respond to signals.
