AP Biology: Unit 3 Review (CED)

Front

Where does the Calvin cycle take place?

Back

The Calvin cycle takes place in the stroma of chloroplasts.

Front

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

Back

The function of the electron transport chain is to establish an electrochemical gradient of protons.

Front

Describe the difference between competitive and noncompetitive inhibitors.

Back

Competitive inhibitors bind to the active site of an enzyme, while noncompetitive inhibitors bind to a different site.

Front

Describe the pathway of electrons in the light reactions.

Back

The pathway of electrons in the light reactions is: H₂O → PSII → ETC → PSI → NADPH.

Front

Where on an enzyme does the substrate bind?

Back

The substrate binds at the active site of the enzyme.

Front

What is the role of ATP synthase in photosynthesis?

Back

ATP synthase synthesizes ATP from ADP and inorganic phosphate using the proton gradient.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

What is the primary pigment involved in photosynthesis?

Back

The primary pigment involved in photosynthesis is chlorophyll.

Front

What is the significance of the thylakoid membrane?

Back

The thylakoid membrane is where the light-dependent reactions of photosynthesis occur.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen, while anaerobic respiration does not.
