Redox

Redox is a process that occurs in many biological instances, e. g, photosynthesis; where water and carbon bioxide are reduced or oxidized. First one molecule received electron, it is said that is reduced; from what... electron from water, then reduced. But photosynthesis is a complex affair: what for light, it is a synonym of energy.

Somebody wrote the following eq. 6 (molecules of carbon bioxide) and 12 (of water) convert in six of oxygen, carbohydrate (an hexa-molecule) and rest six of water, named oxygenic photosynthesis.

This synthesis required photo-energy 6CO2 + 12H2O + Light Energy → C6H12O6 + 6O2 + 6H2O
