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

chloroplasts
where CO2 comes in and O2 goes out

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+
