So now we can describe active transport as the process in which substance are absorbed against the concentration gradient (or we can say substance move from a region of lower concentration to a region of higher concentration) with the help of an enzyme. Active transport takes place both in animal cells and plant cells.

In animal cells, it takes place in the small intestine while absorbing food.

All metabolic processes like Photosynthesis, Respiration etc in the living organisms involve movement of substance in and out of the cells.

The substance move in and out of the cell either by Active Transport or Passive Transport.
