Definitions:

Mediated Transport

The process of moving molecules across a cellular membrane through the use of specific protein channels or carriers.

Carrier Molecules

Molecules that help transport substances across a cell membrane or within the body, similar in function to carrier proteins but can include a broader range of molecules.

Binding Site

A specific region on a protein or enzyme where a particular molecule, such as a substrate, hormone, or drug, can form a stable complex, initiating a biological action.

Secondary Active Transport

involves the movement of substances across a cell membrane utilizing energy indirectly from the electrochemical gradient established by primary active transport.
