during protein kinase activation, enzymes phosphorylate many other enzymes

Adenosine triphosphate, or ATP, is the most common source of energy in cells, and is created through phosphorylation. This can be photophosphorylation (as occurs in photosynthesis) or substrate level phosphorylation, or oxidative phosphorylation.

ATP is created by adding a phosphate group to ADP (adenosine diphosphate), so the answer to your question would be that the energy is used to phosphorylate ADP, turning it into ATP.

You phosphorylate glycerol-3-phosphate (all 5 G3P ) with three ATP and you get ribulose bisphosphate, RuBP, and begin the Calvin cycle again
