Which process requires energy to maintain the unique composition of extracellular and intracellular compartments?
A) Diffusion
B) Osmosis
C) Filtration
D) Active transport

Question

Quizplus · Accepted Answer

Active transport is a process that requires energy to move molecules against their concentration gradient, from an area of lower concentration to an area of higher concentration. This process is necessary to maintain the unique composition of extracellular and intracellular compartments by regulating the movement of ions, nutrients, and other molecules across cell membranes. Diffusion, osmosis, and filtration are passive processes that do not require energy and cannot maintain the unique composition of compartments on their own.
