Are The Types Of Active Transport - What

This was the second type: . ATP didn’t push Suzy directly. Instead, he set up the conditions. Earlier, using primary active transport, ATP had pumped all the sodium ions out of the cell, creating a huge craving for sodium to get back in . That craving—that stored energy in the sodium gradient—was now the engine.

“Nat!” ATP called out. “I have a deal for you. You’re going to flow inside anyway. But if you do it through this special door, you can drag Suzy along with you.” what are the types of active transport

“See?” ATP said. “I didn’t touch Suzy. I just created a sodium traffic jam outside the cell, and then let the sodium rush back in, pulling other molecules with it. That’s secondary active transport. Clever, right?” This was the second type:
