It is required in the Calvin cycle.

3 / 14

3. The majority of ATP in aerobic respiration is produced in:

Glycolysis

Electron Transport Chain

Calvin Cycle

Krebs Cycle

4 / 14

4. Which of the following best describes the Calvin Cycle?

It occurs in the thylakoid membrane.

It produces oxygen as a byproduct.

It is dependent on light energy.

It synthesizes glucose from CO2 and H2O.

5 / 14

5. Which of the following distinguishes anaerobic from aerobic respiration?

Aerobic respiration produces lactic acid.

Anaerobic respiration requires oxygen.

Anaerobic respiration does not involve the Krebs cycle.

Both produce equal amounts of ATP.

6 / 14

6. Which of the following statements is correct about light-dependent and light-independent reactions?

Light-dependent reactions produce glucose.

Light-independent reactions require ATP and NADPH.

Both occur in the stroma.

Light-dependent reactions fix CO2.
