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?”

Later that night, ATP sat by the membrane, exhausted but content. A young vesicle floated by, curious. “So active transport is just moving things against the flow?” it asked. what are the types of active transport

But there was a third, stranger case. As ATP was resting, a small molecule tried to exit the cell against its gradient. It used a different door—an . This time, a calcium ion rushed into the cell down its gradient, and as it entered, it shoved the small molecule out . “See

ATP laughed. “That, my friend, is —a whole different adventure. But it still needs my energy. Everything important does.” That’s secondary active transport
