Answer:
This is for photosynthesis, which is anabolism.
Step-by-step explanation:
The photon which represents the packet of energy from the sun,is used to split water molecules into H+.electrons and oxygen. The Hydrogen ion is used to reduce CO2 to produce CHO, fatty acid and protein in the Calvin cycle.This is photosynthesis.
Therefore, the single reaction is made up of two related reactions, The splitting of water-Photolysis.. which occurs in the daylight.The reaction is therefore called light dependent stage.
While the reduction of the CO2 with the Hydrogen ion , in the presence of ATPs, which takes place in the dark,called light independent stage.
