AP Biology: Unit 3 Review (CED)

Front

What is the pathway of electrons in the light reactions?

Back

H2O → PSII → ETC → PSI → NADPH

Front

What is the function of the electron transport chain between Photosystem II and Photosystem I?

Back

Establish electrochemical gradient of protons.

Front

Where does the Calvin cycle take place?

Back

Stroma.

Front

Where does the electron transport chain take place?

Back

Chloroplasts, prokaryotic plasma membrane, mitochondria (all of the choices).

Front

What is the difference between competitive and noncompetitive inhibitors?

Back

Competitive binds to active site and noncompetitive binds to other site.

Front

What is Photosystem II?

Back

A protein complex in plants that absorbs light and initiates the light reactions of photosynthesis.

Front

What is Photosystem I?

Back

A protein complex that absorbs light and helps in the production of NADPH during photosynthesis.

Front

What is the role of ATP synthase in photosynthesis?

Back

It synthesizes ATP from ADP and inorganic phosphate using the proton gradient established by the electron transport chain.

Front

What is the significance of the proton gradient in photosynthesis?

Back

It drives ATP synthesis during the light reactions.

Front

What are the products of the light reactions of photosynthesis?

Back

ATP, NADPH, and oxygen.
