Question

Is phosphorylation exergonic or endergonic?

Answer 1

Phosphorylation:

1. Phosphorylation is the process of adding phosphorus molecules to the protein molecules from the ATP.
2. The phosphate bond is broken from the ATP to convert into ADP.
3. The energy is stored in the phosphoanhydride bonds.
4. This energy is used in the phosphorylation process.
5. It is an endergonic process as energy is required to add a phosphate molecule to a different biomolecule for forming an additional bond.
