Concentration Gradient

The gradual difference in the concentration of solutes in a solution between two regions.

Carrier Molecule

refers to a molecule that transports substances across a cell membrane, either by passive or active transport mechanisms.

Cotransport

A process by which two substances are simultaneously transported across a cell membrane by a single protein, or complex, often involving the movement of one substance down its concentration gradient to drive the transport of another against its gradient.

  • Attain comprehension of the assorted pathways of membrane transport and their singular specifications, such as active transport, facilitated diffusion, osmosis, phagocytosis, and endocytosis.
