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: -Carrier proteins are responsible for the diffusion of sugars, amino acids, and nucleosides. They are also the proteins that take up glucose molecules and transport them and other molecules (e.g. salts, amino acids, etc.)

Detailed explanation-3: -Carrier proteins can change their shape to move a target molecule from one side of the membrane to the other. Diagram showing how a carrier protein can bind a target molecule on one side of the membrane, undergo a shape change, and release the target molecule on the other side of the membrane.
