The Calvin Cycle

The second of two stages of photosynthesis; a cyclic series of chemical reactions that occur in the stroma of a chloroplast, using the carbon in carbon dioxide, and the ATP and NADPH produced by the light reactions to make the energy-rich sugar molecule, G3P, which is later used to produce glucose.

1

Electron transport chain

A series of electron carrier molecules gang shuttle electrons during the redox reactions that release energy used to make ATP; located in the inner membrane of mitochondria, the thykaloid membrane of chloroplasts, and the plasma membrane of prokaryotes

2

What happens during the light reactions?

Light is captured by chlorophyll and some of the energy is used to break water into hydrogen (which is saved for the dark reactions) and oxygen gas (which is released)

3

What happens during the dark reactions?

Carbon dioxide is combined with hydrogen and energy (which were saved during the light reactions) to form glucose (the MAJOR result of photosynthesis)

4

What does photosystem one produce?

NADPH

5

What does photosystem two produce?

ATP
