Question

Quizplus · Accepted Answer

Active transport involves the use of carrier proteins to move substances against their concentration gradient, requiring the input of energy. This is the opposite of passive transport, which involves the movement of substances from areas of high concentration to areas of low concentration without the use of energy or carrier proteins. Choice A is incorrect because the movement of water is associated with osmosis, which is a type of passive transport. Choice B is also incorrect because active transport does require the input of energy. Choice C describes passive transport, not active transport.
