Photosynthesis! (Part 1)

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 is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily from the blue and red wavelengths, and reflects green light.

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

Where do light reactions occur in the chloroplast?

Back

Light reactions occur in the thylakoid membranes of the chloroplast.

Front

Where does the Calvin Cycle take place?

Back

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

Front

What is the primary function of the light reactions?

Back

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

Front

What is produced as a byproduct of the light reactions?

Back

Oxygen is produced as a byproduct of the light reactions when water is split.

Front

What is the electron transport chain?

Back

The electron transport chain is a series of protein complexes in the thylakoid membrane that transfer electrons from water to NADP+, creating a proton gradient that drives ATP synthesis.

Front

What is the final electron acceptor in the light reactions?

Back

The final electron acceptor in the light reactions is NADP+, which is reduced to NADPH.

Front

What is the role of ATP synthase in photosynthesis?

Back

ATP synthase is an enzyme that synthesizes ATP from ADP and inorganic phosphate, using the proton gradient created during the light reactions.
