Question

Is ATP used in secondary active transport?

Answer 1

Secondary active transport:

1. Secondary active transport or coupled transport or cotransport is the transport that uses the energy to transport particles across a membrane.
2. In primary active transport, molecules are transported by the breaking down of ATP.
3. In secondary active transport, the concentration gradient of one molecule provides energy for the transport of another molecule against the concentration gradient.
4. The coupling of ATP does not take place immediately.
5. It relies on the electrochemical potential difference created by pumping particles in and out of the cell.
6. The secondary active transport does not require ATP directly, but the electrochemical gradient produced by the primary active transport is utilized by the ATP.
