11. How does active transport differ from all other forms of transportation?

A. It creates an equilibrium shift

B. It maintains homeostasis

C. It shifts from high to low

D. It requires energy

The Answer is D It requires energy

Explanation:

The movement of ions are assisted enzymes which uses energy.

Though both active transport and passive transport involve ion movement and use ion channels to move ions across the cell membrane, in or out of the cell.

Passive Transport (or Diffusion) moves ions from high concentration to low, using no metabolic energy. Active Transport moves ions from low concentration to high, using metabolic energy in the form of ATP.

So the answer is C.
