Question

Quizplus · Accepted Answer

Active transport uses cellular energy (ATP) to move molecules from areas of lower concentration to areas of higher concentration, which is against the concentration gradient. This process requires the use of protein pumps or channels in the cell membrane. It is essential for many physiological processes, including the uptake of nutrients and the removal of waste products from the cell.
