8.8carbon dioxide how is it solve
Answers
Carbon dioxide fixation reactions in photosynthesis are divided into three reaction groups (Column Fig. 8-2). The first is a group of reactions in which ribulose 1,5-bisphosphate incorporates carbon dioxide (CO2) to produce two molecules of phosphoglycerate (top of Fig. 8-6) and is catalyzed by ribulose 1,5-bisphosphate carboxylase/oxygenase (a.k.a. RuBisCO*10). The second is a group of reactions that use ATP and NADPH to produce and release sugar phosphates from the cycle, consequently synthesizing starch and sucrose. The third is a pathway in which various sugar phosphates are connected by equilibrium reactions, regenerating ribulose 5-phosphate - a precursor of ribulose 1,5-phosphate. These reactions are known as the Calvin cycle or the reductive pentose phosphate cycle.
