PHOTOSYNTHESIS: Calvin Cycle
2
Objectives:
State the specific products generated from water, sunlight and carbon dioxide.
Explain the importance of water, sunlight and carbon dioxide in the process of photosynthesis.
3
CALVIN CYCLE (Light-Independent Reaction)
After the sun's energy is converted and packaged into ATP and NADPH, the plant cell has the fuel needed to build food called carbohydrate molecules. How is this carbohydrate formed?
4
CO2 + RuBP--> 6-carbon molecule
6-carbon molecule --> 2 3-PGA
CARBON FIXATION
5
Multiple Choice
Which molecule does CO2 attach itself to?
ATP
NADPH
oxygen
Ribulose 1,5-bisphosphate (RuBP)
6
Multiple Choice
The attachment of CO2 and RuBP results to a 6-carbon molecule. What happens next to this 6-carbon molecule?
It splits into two 3-carbon molecules
It becomes G3P.
It turns into PGAL molecule.
It turns into glucose phosphate.
7
Multiple Choice
In the Calvin cycle, carbon from CO2 is added to one molecule of RuBP to create _____
