biology topic 5
photosynthesis
light independent reactions
occurs in the stroma of the plant cell
CO2 is fixed into lipids, carbs and amino acids
it doesn't require light but it does need the products of LDR
the reaction will stop if ATP and reduced NADP are not available
ribulose bisphosphate carboxylase (RuBisCO)
6C
Glycerate 3-Phosphate
Triose Phosphate
ribulose bisphosphate (RuBP)
loss of 1C
this C can be used to create molecules such as glucose, amino acids and lipids
ATP
ADP + Pi

co2
calvin cycle
this reaction doesn't need light but needs the products of LDR
glycolysis
stage one- carbon fixation
stage three- regeneration
stage 2- reduction of GP to form TP
