AP Biology Photosynthesis Review

Front

What is the primary function of the Calvin cycle?

Back

The primary function of the Calvin cycle is to produce simple sugars from carbon dioxide.

Front

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

Back

The primary function of the light reactions of photosynthesis is to produce NADPH and ATP.

Front

What role do pigments other than chlorophyll play in photosynthesis?

Back

Pigments other than chlorophyll absorb different wavelengths of light, allowing for a broader spectrum of light energy to be captured.

Front

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

Back

One sugar molecule is produced from every six molecules of carbon dioxide that enter the Calvin cycle.

Front

What is the overall goal of photosynthesis?

Back

The overall goal of photosynthesis is to convert light energy into chemical energy stored in 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

Where do the light reactions of photosynthesis take place?

Back

The light reactions of photosynthesis take place in the thylakoid membranes of the chloroplasts.

Front

What are the products of the light reactions?

Back

The products of the light reactions are NADPH, ATP, and oxygen.

Front

What is the role of chlorophyll in photosynthesis?

Back

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

Front

What is the significance of NADPH in photosynthesis?

Back

NADPH is used as a reducing agent in the Calvin cycle to help convert carbon dioxide into glucose.
