- Source of chemical energy
1-carbon fixation, 2-reduction, 3-regeneration
What is carbon fixation?
Incorperation of CO2 into organic molecules (hydrocarbons)
Carbon fixation is catalysed by...
Rubisco (enzyme)- 1 6-C sugar breaks down into 2 phosphoglycerates (PGAs)
What is reduction?
Where NADPH and ATP from light reactions are used (6 ATP and 6 NADPH)
What is regenerated?
Starting material- ribulose biphosphate (RuBP) *requires 3 ATP
3 CO2, 6 NADPH, 9 ATP
1 PGAL, 9 ADP, 9 Pi, 6 NADP
How many times does the cycle go to make 1 PGAL?
3 (6 for a glucose)
More potential and chemical energy
