Photosynthesis Reactions

What happens to the oxygen that is produced during the light dependent reaction?

• It is changed into CO2 by the enzyme rubisco

• It is used in the light independent reaction

• It is released from the plant through the stomata

• It is converted into glucose

• ATP

• chlorophyll

• NADPH

• xanthophyll
