AP Bio Insta-Review Topic 3.5: Photosynthesis

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin Cycle).

Front

Where do light-dependent reactions occur?

Back

Light-dependent reactions occur in the thylakoid membranes of chloroplasts.

Front

What is the primary pigment involved in photosynthesis?

Back

The primary pigment involved in photosynthesis is chlorophyll.

Front

What is produced during the light-dependent reactions?

Back

During the light-dependent reactions, ATP and NADPH are produced, along with oxygen as a byproduct.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily in the blue and red wavelengths, which is essential for the light-dependent reactions.

Front

Where does the Calvin Cycle take place?

Back

The Calvin Cycle takes place in the stroma of chloroplasts.

Front

What is the main purpose of the Calvin Cycle?

Back

The main purpose of the Calvin Cycle is to convert carbon dioxide into glucose using ATP and NADPH produced in the light-dependent reactions.

Front

What is the significance of oxygen production in photosynthesis?

Back

Oxygen produced during photosynthesis is essential for the survival of aerobic organisms and contributes to the Earth's atmosphere.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.
