Detailed explanation-1: -Carrier proteins are responsible for the facilitated diffusion of sugars, amino acids, and nucleosides across the plasma membranes of most cells.

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: -All channel proteins and many carrier proteins allow solutes to cross the membrane only passively (“downhill”), a process called passive transport, or facilitated diffusion.

Detailed explanation-4: -Active transport is a kind of cellular transport in which substances like amino acids, glucose and ions are transported across cell membranes to a region that already has a high concentration of such substances.

Detailed explanation-5: -Glucose uses a carrier protein to cross the plasma membrane by facilitated diffusion. common glucose transporters which help in glucose transfer are GLUTs.
