AP Photosynthesis

Front

What is the role of Rubisco in photosynthesis?

Back

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

Front

What happens to NADP+ during the light reaction?

Back

NADP+ is reduced during the light reaction.

Front

How many sugar molecules are produced from every six molecules of carbon dioxide in the Calvin cycle?

Back

1 sugar molecule is produced.

Front

What reactants do plants use for the light reaction?

Back

Plants use water and NADP+ for the light reaction.

Front

Which of the following does NOT contribute to ATP production during the light reaction?

Back

NADPH donating electrons does NOT contribute to ATP production.

Front

What is the Calvin cycle?

Back

The Calvin cycle is a series of biochemical reactions that take place in the stroma of chloroplasts, where CO2 is converted into glucose.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light reactions and the Calvin cycle.

Front

What is the primary function of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, which is used to energize electrons during the light reactions.

Front

What is produced during the light reactions of photosynthesis?

Back

The light reactions produce ATP, NADPH, and oxygen.

Front

What is the significance of the hydrogen ion gradient in ATP production?

Back

The hydrogen ion gradient drives ATP synthase to produce ATP during the light reactions.
