Question

Diffusion takes place according to concentration gradient. Is it possible for materials to move against concentration gradient gradient? If yes mention why these is required.​

Answer 1

Explanation:

The difference in the concentration of a substance between two areas is called the concentration gradient . The bigger the difference, the steeper the concentration gradient and the faster the molecules of a substance will diffuse. The direction of diffusion is said to be 'down' or 'with' the concentration gradient.
