AP: Photosynthesis (LDR & Calvin cycle)

Front

What is the role of Rubisco in photosynthesis?

Back

Rubisco is an enzyme that catalyzes the reaction of carbon fixation, where CO2 is connected to ribulose bisphosphate (RuBP) during the Calvin cycle.

Front

How do protons (H+) move into the thylakoid during photosynthesis?

Back

Protons (H+) move into the thylakoid due to the movement of electrons through the electron transport chain.

Front

What is a false statement about the Calvin cycle?

Back

The Calvin cycle does not produce carbon dioxide; it uses CO2 to produce glucose.

Front

How is ATP formed in the light-dependent reactions of photosynthesis?

Back

ATP is formed through the process of chemiosmosis, which involves the passive transport of H+ ions from a high concentration to a low concentration.

Front

Which of the following is NOT a product of the light reactions of photosynthesis?

Back

Glucose is not a product of the light reactions; it is produced in the Calvin cycle.

Front

What are the two main stages of photosynthesis?

Back

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

Front

What is the primary function of the light-dependent reactions?

Back

The primary function of the light-dependent reactions is to convert light energy into chemical energy in the form of ATP and NADPH.

Front

What is the main product of the Calvin cycle?

Back

The main product of the Calvin cycle is glucose, which is synthesized from carbon dioxide.

Front

What is the significance of the electron transport chain in photosynthesis?

Back

The electron transport chain is significant because it facilitates the movement of electrons, leading to the generation of a proton gradient that drives ATP synthesis.

Front

What is chemiosmosis in the context of photosynthesis?

Back

Chemiosmosis is the process by which ATP is produced in the light-dependent reactions, utilizing the energy from the proton gradient across the thylakoid membrane.
