Active transport: Learn what active transport

Learn what active transport is, how it works, and why it is important for cells. Find out the differences between primary and secondary active transport , and see examples and diagrams. 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. Primary active transport moves ions across a membrane and creates a difference in charge across that membrane, which is directly dependent on ATP. Secondary active transport does not directly require ATP; instead, it is the movement of material due to the electrochemical gradient established by primary active transport . “ Active Transport – the unsung hero of cellular operations, ensuring that our cells never run out of stock.” Just like a diligent stock replenisher in a supermarket, active transport is constantly at work, moving molecules from a region of lower concentration to a region of higher concentration. But how does it happen? Buckle up, as we journey into the heart of our cells to explore this vital process.
