Explain carboxylation step of Calvin cycle.
Answers
fabulous biphosphate accept the atmospheric CO2 in the presence of enzyme are you RUBP carboxylase to form 6 carbon unstable compound this unstable compounds in splits into three carbon compound PGA that means phosphoglyceric acid the reaction require mg and H2O
" The carboxylation step of Calvin cycle refers to the fixation of carbon from carbon dioxide.
During this step, carbon dioxide forms an unstable six carbon intermediate on condensation with ribulose-1,5-bisphosphate.
The unstable intermediate then splits into two molecules of 3-phosphoglyceric acid.
The whole reaction is catalysed by RuBisCo (ribulose-1,5-bisphosphate carboxylase/oxygenase) enzyme. This step occurs in the stroma of chloroplasts.
This reaction is the rate limiting step for production of hexose sugars in plants.
