Detailed explanation-1: -Membrane transport proteins fulfill an essential function in every living cell by catalyzing the translocation of solutes, including ions, nutrients, neurotransmitters, and numerous drugs, across biological membranes.
Detailed explanation-2: -Channel proteins, gated channel proteins, and carrier proteins are three types of transport proteins that are involved in facilitated diffusion. A channel protein, a type of transport protein, acts like a pore in the membrane that lets water molecules or small ions through quickly.
Detailed explanation-3: -Channel proteins, voltage-gated ion channels, aquaporins, carrier proteins, sodium-potassium pumps, GLUT1, proton pump, calcium ATPase, and so on are examples of such proteins.
Detailed explanation-4: -Carrier proteins are proteins involved in the movement of ions, small molecules, or macromolecules, such as another protein, across a biological membrane. Carrier proteins are integral membrane proteins; that is, they exist within and span the membrane across which they transport substances.
