Active transport is the movement of a substance from a region of low concentration to a region of high concentration against the concentration gradient.
About Active Transport
- Active transport requires energy to move a substance against the concentration gradient.
- Active transport is an essential process for all living organisms. It is used to take in nutrients when there is not a high enough concentration to diffuse into the organism.
- Active transport allows organisms to take in nutrients more quickly and efficiently than diffusion.
