AP Biology Photosynthesis

Front

What is the function of NADP+ in photosynthesis?

Back

NADP+ serves as an electron carrier, transporting electrons during the light reactions.

Front

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

Back

1 sugar molecule is produced from every six molecules of carbon dioxide.

Front

Where do the light reactions of photosynthesis occur?

Back

The light reactions occur in the thylakoid membrane.

Front

Where do the dark reactions (Calvin cycle) take place?

Back

The dark reactions take place in the stroma.

Front

What is the role of pigments other than chlorophyll in chloroplasts?

Back

Other pigments absorb different wavelengths of light, allowing for a broader spectrum of light absorption.

Front

What is the primary function of the light reactions in photosynthesis?

Back

The primary function is to produce NADPH and ATP.

Front

What are the two main stages of photosynthesis?

Back

The two main stages are the light reactions and the Calvin cycle (dark reactions).

Front

What is the significance of ATP in photosynthesis?

Back

ATP provides the energy required for various biochemical reactions in the Calvin cycle.

Front

What is the role of carbon dioxide in photosynthesis?

Back

Carbon dioxide is a reactant in the Calvin cycle, where it is fixed into organic molecules.

Front

What is the importance of chlorophyll in photosynthesis?

Back

Chlorophyll is the primary pigment that absorbs light energy, primarily in the blue and red wavelengths.
