Photosynthesis and respiration

? Collectively, photosynthesis and respiration control bioelemental cycling.

Photosynthesis:

6CO2 + 12H2O

Sunlight C6H12O6 + O2 + 6H2O + heat

Respiration:

C6H12O6 + 6O2

6CO2 + 6H2O + heat

? Photosynthesis is initiated by the absorption of light energy by pigments or photochemically reactive proteins. The absorbed light energy is passed from the light harvesting pigments (antenna) to the photosynthetic reaction centers via the flow of electrons.
