: A transmembrane protein, often called a "pump" or ATPase, hydrolyzes ATP to release energy. This energy causes a conformational change in the protein, allowing it to "push" specific ions or molecules through the membrane.
This pump is found in almost all animal cell membranes. For each ATP molecule broken down, it moves: primary active transport vs secondary
In summary, the Primary Active Transport Team has the power to directly move visitors against the crowd flow using their special wristbands (ATP), while the Secondary Active Transport Team works with visitors who are already moving in the right direction to indirectly move other molecules against their concentration gradient. : A transmembrane protein, often called a "pump"
