WebApr 9, 2024 · To move substances against a concentration or electrochemical gradient, the cell must use energy. This energy is harvested from ATP generated through the cell’s metabolism. Active transport mechanisms, collectively called pumps, work against electrochemical gradients. Small substances constantly pass through plasma membranes. Webecule, adenosine-5'-triphosphate (ATP), may assess the energy state in cells. Cellular ATP is an important determinant of cell death by apoptosis or necrosis.1 Cells stay alive as long as a certain level of ATP is maintained. When ATP falls below this level, apoptosis is activated.2 A severe drop in cellular ATP will result in cellular necrosis.
