AP Bio Photosynthesis

Front

What is the primary purpose of the H+ concentration gradient in photosynthesis?

Back

To generate ATP.

Front

What role does ATP Synthase play in photosynthesis?

Back

ATP Synthase is a membrane protein that allows hydrogen ions (H+) to escape the thylakoid, facilitating ATP production.

Front

Which process in photosynthesis is directly driven by light energy?

Back

The removal of electrons from membrane-bound chlorophyll molecules.

Front

What is the function of Rubisco in the Calvin cycle?

Back

Rubisco is important for carbon fixation, where CO2 is connected to RUBP.

Front

What would happen if the proton (H+) pump in the thylakoid was not functioning?

Back

ATP could not be made during the light reaction.

Front

Define 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 light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

Where do the light-dependent reactions of photosynthesis occur?

Back

In the thylakoid membranes of chloroplasts.

Front

What is the main product of the light-dependent reactions?

Back

ATP and NADPH.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, which is used to energize electrons.
