What phrase describes a nutrient transport system that behaves similar to enzymes, requires energy and moves the nutrient in one direction?

Question

Quizplus · Accepted Answer

Active transport requires energy (in the form of ATP) and moves substances against their concentration gradient, similar to enzymes which also require energy and act in a specific direction. Simple diffusion, facilitated diffusion, and exchange diffusion do not require energy and/or do not move substances in a specific direction.
