Photosynthesis Review AP Biology

Front

What are the products of the light reactions of photosynthesis that are required by the Calvin cycle?

Back

ATP and NADPH are the products of the light reactions that are used in the Calvin cycle.

Front

What role does Rubisco play in photosynthesis?

Back

Rubisco is crucial for carbon fixation, where it catalyzes the reaction of CO2 with RUBP during the Calvin cycle.

Front

Where does the Calvin cycle occur?

Back

The Calvin cycle takes place in the stroma of the chloroplast.

Front

What happens to protons during the electron transport chain (ETC) in photosynthesis?

Back

Protons are pumped from the stroma to the lumen, creating a proton gradient necessary for ATP synthesis.

Front

What is the main source of energy for all life on Earth?

Back

The main source of energy for all life comes from the sun.

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.

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

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment that absorbs light energy, primarily in the blue and red wavelengths, and is essential for the light reactions.

Front

What is the significance of the proton gradient in photosynthesis?

Back

The proton gradient created during the light reactions is used to drive ATP synthesis through ATP synthase.

Front

What is the formula for photosynthesis?

Back

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