Photosynthesis 4

What is the main product formed when photons are absorbed at Photosystem I (PSI)?

• NADPH

• ATP

• NADP+

• Low-energy electrons (LEE)

What is the main purpose of the Calvin Cycle in photosynthesis?

• To convert CO2 into oxygen

• To convert CO2 into carbohydrates

• To convert water into oxygen

• To convert sunlight into ATP

Where does the Calvin Cycle take place within the chloroplast?

• Thylakoid membrane

• Stroma

• Grana

• Outer membrane

During the daytime, what happens to the sucrose in the plant?

• It is stored in the leaves

• It is continually exported from leaves

• It is converted back to starch

• It is used for photosynthesis

What is the overall energy conversion in photosynthesis?

• Photon energy to CPE of ATP

• Photon energy to CPE of carbohydrates

• Photon energy to PPE of proton gradient

• Photon energy to reducing power of NADPH
