Active transport is transport in an energetically

Question

Quizplus · Accepted Answer

Active transport always moves substances against their concentration gradient, which is energetically unfavorable. Therefore, it requires a source of energy. In active transport, energy can be obtained from the hydrolysis of ATP, but it can also be derived from other sources, such as the exchange of one molecule for another, the flow of an ion gradient, or the absorption of light by a pigment. This is why option B is the best answer, as it acknowledges that active transport can be driven by various sources of energy, not just the hydrolysis of ATP.
