Question

Quizplus · Accepted Answer

All of the molecules mentioned (hormones and growth factors, enzymes, and blood-borne proteins carrying certain nutrients) can be internalized by receptor-mediated endocytosis. This is a mechanism by which cells can selectively take up specific molecules from their environment by using specialized receptors on their surface. The molecules bind to the receptors, triggering the formation of a clathrin-coated pit and ultimately the internalization of the receptor-ligand complex into the cell through an endocytic vesicle. This mechanism is important for nutrient uptake, signaling, and other cellular processes.
