Active transport involves ________.

Question

Quizplus · Accepted Answer

Active transport involves the pumping of solutes across the membrane, which requires energy input. Unlike passive transport, active transport moves molecules against their concentration gradient, from an area of lower concentration to an area of higher concentration. This process is often fueled by the hydrolysis of ATP. Option A is incorrect because diffusion is a passive transport process that does not require energy input. Option C is incorrect because ATP production is not synonymous with active transport. Option D is incorrect because transport of solute down a concentration gradient would be indicative of passive transport rather than active transport.
