Photosynthesis 3

What is the role of regular chlorophyll in the light reactions of photosynthesis?

• Absorbs light energy and transfers it to the reaction center

• Directly converts light energy into chemical energy

• Produces ATP through photophosphorylation

• Fixes carbon dioxide into glucose

What is produced as a result of the water-splitting reaction in Photosystem II (PSII)?

• ATP and NADPH

• Glucose and oxygen

• 4H+, 4e- and O2

• 2H+, 2e- and O2

What happens to high-energy electrons (HEE) after they leave Photosystem II (PSII)?

• They enter Photosystem I (PSI) as low-energy electrons (LEE).

• They are released into the stroma.

• They enter Photosystem I (PSI) as high-energy electrons (HEE).

• They are used to split water molecules.

Where does the transfer of high energy electrons (HEE) occur in Photosystem I (PSI)?

• PSI reaction centre complex

• PSI light harvesting complex

• Thylakoid lumen

• Stroma

Which component links Photosystem II (PSII) with Photosystem I (PSI) in the electron transport chain?

• Series of chlorophylls

• NADPH

• Series of electron carriers

• Oxygen-evolving complex (OEC)
