Answer:
B)the energy required
Explanation:
The difference between active and passive transport is in the amount of energy they both require.
- Active transport requires energy to move molecules such as ATP and ions against a concentration gradient.
- Passive transport moves molecules from higher concentration region to one with lower concentration without requiring energy.
Energy is the ability to do work. In passive transport, energy is not used. But in active transport, energy is required.
