Question

4. Where does an active-transport process occur in an
animal?​

Answer 1

Because energy is required in this process, it is known as 'active' transport. Examples of active transport include the transportation of sodium out of the cell and potassium into the cell by the sodium-potassium pump. Active transport often takes place in the internal lining of the small intestine.

Answer 2

Answer:

Active transport requires energy from respiration to move the particles against the concentration gradient. Active transport takes place both in animal cells and plant cells. In animal cells, it takes place in the small intestine while absorbing food.
