17. how does active transport differ from all other forms of transportation? a. it shifts from high to low b. it maintains homeostasis c. it creates an equilibrium shift d. it requires energy

Option D,  It requires energy

Explanation:

Active transport is a mechanism by which a substance move against the concentration gradient i.e from regions of low concentration to regions of high concentration. In order to do move against the gradient lot of energy is required which is pumped in by the energy molecule ATP produced during the cellular respiration.

While in other form of transportation i.e passive, a substance moves from the region of high concentration to the region of low concentration and hence no energy input is required.

Thus, option D is correct
