Secondary active transport is a bit more "resourceful." It doesn't use ATP directly. Instead, it hitches a ride on the energy created by primary active transport. When a pump creates a high concentration of ions on one side of a membrane, those ions "want" to flow back in. The cell uses that downward flow to pull another molecule along with it. There are two main sub-types:
Both molecules move in the same direction. For example, as sodium ions move back into a cell, they often bring glucose molecules with them. what are the types of active transport
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. Secondary active transport is a bit more "resourceful
This is how the cell "eats" or "drinks." The membrane folds inward to bring materials into the cell. The cell uses that downward flow to pull
