State the Formula for Photosynthesis and What is Happening?

Carbon Dioxide + Water --[Light]--> Glucose + Oxygen 6CO² + 6H²O --> C6H12O6 + 6O² -This is an Endothermic Reaction, so Energy is Taken From the Environment [Surroundings get Colder] -Also, 2 Stages are seen. The First is the Light Energy Splits up the Water and Oxygen into Hydrogen + Oxygen Ions [Photolysis] and the Second Stage is Carbon Dioxide reacting with the Ions to make Glucose and Oxygen Gas.
