AP Bio Unit 7.1

What is the primary function of the Calvin cycle?

• regenerate ATP for use in the light reactions of photosynthesis
• produce carbon dioxide for use in the light reactions of photosynthesis
• produce oxygen by oxidizing water
• produce simple sugars from carbon dioxide

If the proton (H+) pump in the thylakoid was not working which molecule could not be made during the light reaction?

• NADPH

• ATP

• Water

• Oxygen gas

• hydrogen ion gradient

• electron energy from photosystem II

• NADPH donating electrons

Where is the most easily accessible energy stored in an ATP molecule?

• between the 1st and 2nd phosphate groups

• between the adenine and ribose groups

• between the 2nd and 3rd phosphate groups

• between the ribose and the 1st phosphate groups
