Calvin Cycle Quiz

Which compound is NOT directly involved in the light-dependent reactions?

• ATP

• NADPH

• Glucose

• Chlorophyll

What is the overall photosynthesis equation?

• 6CO2 + 6H2O + light energy → C6H12O6 + 6O2

• 6O2 + 6H2O + light energy → C6H12O6 + 6CO2

• C6H12O6 + 6O2 → 6CO2 + 6H2O + light energy

• 6CO2 + C6H12O6 → 6H2O + 6O2 + light energy
