What Are The Two Major Types Of Active Transport |best| Now

Unlike passive transport (think diffusion or osmosis, where things just "flow" downhill), active transport requires —specifically, ATP (the cellular currency).

The Sodium-Potassium Pump (Na⁺/K⁺ ATPase) . This pump is working constantly in your nerve and muscle cells. It grabs 3 sodium ions (inside the cell), uses one ATP to change shape, and flings them outside. Then it grabs 2 potassium ions (outside) and brings them in. what are the two major types of active transport

But not all active transport is the same. Scientists split it into two major types based on how that energy is used. Unlike passive transport (think diffusion or osmosis, where

Here, the cell doesn’t use ATP directly. Instead, it harnesses the stored in an ion gradient that was already created by primary active transport. One molecule rides downhill (with its gradient), and that "pull" drags a second molecule uphill (against its gradient). It grabs 3 sodium ions (inside the cell),
