Question

What is a solute-carrier complex?

Answer 1

SOLUTE-CARRIER COMPLEX

1. In active absorption, the carrier molecule reacts chemically with the solute (ion) to be transported across the cell membrane.
2. The solute ion to be absorbed combines with the specific carrier to form the solute-carrier complex.
3. It then moves across the membrane, and on reaching the cytoplasm, it dissociates to release the solute ion.
4. It is then activated and goes back to the surface to combine with another solute ion.
5. In the entire process, energy is required in the form of ATP.
