Photosynthesis AP Bio Review

Front

What is the main purpose of photosynthesis?

Back

To convert light energy into chemical energy stored in glucose.

Front

What are the two main stages of photosynthesis?

Back

Light reactions and the Calvin cycle.

Front

What is produced during the light reactions of photosynthesis?

Back

ATP, NADPH, and oxygen.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily in the blue and red wavelengths.

Front

What is a granum?

Back

A stack of thylakoids within the chloroplast.

Front

What is the function of ATP synthase in photosynthesis?

Back

To synthesize ATP from ADP and inorganic phosphate using the energy from H+ ions.

Front

What color of light is least absorbed by chlorophyll?

Back

Green light.

Front

What is the significance of the absorption spectrum in photosynthesis?

Back

It shows which wavelengths of light are absorbed by chlorophyll and other pigments.

Front

What is the role of water in the light reactions of photosynthesis?

Back

Water is split to provide electrons, protons, and oxygen.

Front

What is the Calvin cycle?

Back

The set of chemical reactions that take place in the chloroplasts during photosynthesis, where carbon dioxide is fixed into glucose.
