Front

What is the role of Rubisco in photosynthesis?

Back

Rubisco is important in carbon fixation when CO2 is connected to RUBP during the Calvin cycle.

Front

What molecule is produced during the light reaction of photosynthesis that is affected by the proton (H+) pump in the thylakoid?

Back

ATP.

Front

How does the energy yield of fermentation compare to that of aerobic respiration?

Back

Aerobic respiration results in more energy than fermentation.

Front

What is the function of NADP+ in photosynthesis?

Back

NADP+ acts as an electron carrier.

Front

Which process in cellular respiration is the largest contributor to the release of CO2?

Back

The Citric Acid Cycle (Krebs Cycle).

Front

What are the two main stages of photosynthesis?

Back

Light-dependent reactions and the Calvin cycle.

Front

What is the primary purpose of the light-dependent reactions in photosynthesis?

Back

To convert solar energy into chemical energy in the form of ATP and NADPH.

Front

What is the main product of the Calvin cycle?

Back

Glucose (or G3P, which can be converted into glucose).

Front

What is the significance of the proton gradient in the thylakoid membrane?

Back

It drives ATP synthesis during the light reactions of photosynthesis.

Front

What is the difference between aerobic respiration and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more energy, while anaerobic respiration occurs without oxygen and produces less energy.
