Welcome to Photosynthesis This is the process in which light energy is converted to chemical energy.

The Inside of a Plant Cell chloroplasts where CO2 comes in and O2 goes out

The Inside of a Chloroplast

Pigments absorb light energy = hc λ

6CO2 + 12H20 + light → C6H12O6 + 6O2 + 6H2O light + H2O + ADP + Pi + NADP+ + → ½O2 + ATP + NADPH + H+ 6CO2 + 18ATP + 12NADPH + 12H+ → C6H12O6 + 6H2O + 18ADP + 18Pi + 12NADP+

light + H2O + ADP + Pi + NADP+ + 2H+ → 2H+ + ½O2 + ATP + NADPH + H+

6CO2 + 18ATP + 12NADPH + 12H+ → C6H12O6 + 6H2O + 18ADP + 18Pi + 12NADP+

Harvesting light with a photosystem

6CO2 + 18ATP + 12NADPH + 12H+ → C6H12O6 + 6H2O + 18ADP + 18Pi + 12NADP+

6CO2 + 18ATP + 12NADPH + 12H+ → C6H12O6 + 6H2O + 18ADP + 18Pi + 12NADP+
