Carrier Molecule
A molecule that facilitates the transport of another molecule across a cell membrane, often requiring energy.
Cellular Energy
Energy stored in the cells that is necessary for various functions including metabolism, chemical synthesis, and muscular contraction, mainly produced in the form of ATP.
Facilitated Diffusion
A process of passive transport, helped by integral membrane proteins, where molecules move across a biological membrane from higher concentration to lower concentration without needing cellular energy.
