Active Transport Definition
Active transport is a cellular process that uses energy to move molecules or ions from a region of lower concentration to a region of higher concentration against their concentration gradients across the cell membrane.
Active Transport
Active transport is a cellular process that uses energy mainly in the form of ATP, to move molecules or ions against their concentration gradients. It includes primary active transport, which directly uses energy for transport, and secondary active transport, which utilizes an electrochemical gradient to move other substances. It is essential for many physiological processes, including nutrient absorption in the digestive system, the transmission of nerve impulses, and the regulation of ion concentrations in cells.
