Active Transport EXPLAINED | Primary vs Secondary

The video tutorial explains the two types of active transport: primary and secondary. It begins with an overview of ion distribution across the plasma membrane, using the sodium-potassium pump as an example of primary active transport. The pump uses ATP to move sodium and potassium ions against their concentration gradients. Secondary active transport is then discussed, highlighting how it relies on the concentration gradients established by primary transport to move substances like glucose without directly using ATP.
