AP Bio Insta-Review Topic 3.5: Photosynthesis

Front

What is the primary function of photosynthesis?

Back

To convert light energy into chemical energy stored in glucose.

Front

What are the two main stages of photosynthesis?

Back

Light-dependent reactions and the Calvin Cycle.

Front

Where do the light-dependent reactions of photosynthesis occur?

Back

In the thylakoid membranes of chloroplasts.

Front

What is produced during the light-dependent reactions?

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 the Calvin Cycle also known as?

Back

The light-independent reactions or dark reactions.

Front

What is the main product of the Calvin Cycle?

Back

Glucose (or G3P, a three-carbon sugar).

Front

How many ATP molecules are used in one turn of the Calvin Cycle?

Back

3 ATP molecules.

Front

What is the significance of cyanobacteria in the context of photosynthesis?

Back

Cyanobacteria are believed to be the first organisms to perform photosynthesis, producing oxygen.

Front

What is the role of water in photosynthesis?

Back

Water provides electrons and protons for the light-dependent reactions and releases oxygen as a byproduct.
