Honors Chapter 7

Front

What process splits water to release oxygen?

Back

Light reactions.

Front

What is the path of excited electrons in the light reactions?

Back

Water -> Photosystem II -> Electron Transport Chain -> Photosystem I -> NADPH.

Front

What is the role of pigments in photosynthesis?

Back

Pigments absorb certain wavelengths of light.

Front

How does carbon dioxide concentration affect photosynthesis?

Back

More carbon dioxide causes photosynthesis to run faster until it reaches a maximum rate.

Front

What happens to NADPH in the Calvin cycle?

Back

NADPH is oxidized to NADP+.

Front

What is the main product of the light reactions?

Back

Oxygen and ATP/NADPH.

Front

What is the Calvin cycle primarily responsible for?

Back

Fixing carbon dioxide into glucose.

Front

What are the two main stages of photosynthesis?

Back

Light reactions and the Calvin cycle.

Front

What is the function of photosystem II?

Back

To absorb light and split water molecules.

Front

What is the electron transport chain's role in photosynthesis?

Back

To transfer electrons and create a proton gradient for ATP synthesis.
