Photosynthesis Flashcard

Front

Where do the light-dependent reactions occur?

Back

thylakoid membrane of chloroplast

Front

What is the source of the electrons in the electron transport chain?

Back

chlorophyll

Front

How are electrons that are released from the water molecules used?

Back

to replace energized electrons that leave the chlorophyll molecules

Front

What role do these electrons play?

Back

provide energy to move hydrogen ions into the thylakoid and to produce molecules of NADPH

Front

Where in the chloroplast do light-independent reactions occur?

Back

stroma of chloroplast

Front

Where are the ATP and NADPH coming from?

Back

light-dependent reactions

Front

Why are these reactions called a cycle?

Back

The five-carbon molecule of the process is regenerated, so the cycle continues.

Front

Why must the Calvin cycle occur more than once to build a sugar molecule?

Back

because only one carbon dioxide molecule, and so just one carbon, is added to the Calvin cycle with each turn.
