water→NADPH→Calvin cycle

Question 9

Why is NADPH important in photosynthesis?

Answer 9

It carries hydrogen atoms and high-energy electrons for producing organic molecules

Question 10

What do the light-independent reactions produce?

Answer 10

ATP & NADPH

Question 11

Plants use energy from the sun to convert carbon dioxide and water into what?

Answer 11

Glucose

Question 12

During this process, carbon from carbon dioxide (CO2) is incorporated into organic molecules.

Answer 12

Calvin Cycle
