Phase 1:碳的固定 (Carbon fixation) Calvin cycle将每个个别的CO2附著在一个称为ribulose bisphosphate(简称 RuBP)的五碳糖上以合并之。催化这起始步骤的酶是RuBP carboxylase,或 rubisco。(这是在叶绿体中最丰富的蛋白质,而且也可能是地球上最丰富的蛋白质)这个反应的产物是一种含六个碳而且非
The Calvin cycle achieve this through three phases. Phase 1: Carbon fixation In the carbon fixation phase, each CO2 molecule is attached to a five-carbon sugar, ribulose bisphosphate (RuBP). Rubisco is the most abundant protein in chloroplasts and is the most abundant protein on Earth. The ...
The cycle can be divided into three phases. The first phase is carboxylation, catalysed by ribulose-1,5-bisphosphate oxygenase (Rubisco). The second is the reductive phase, in which glycerate-3-P is reduced to triose-P (glyceraldehyde-3-P (GAP) and dihydroxyacetone-P (DHAP)) by the ...
Chloroplast ATP level was higher in mutant plants during the light-induction phase of photosynthesis. Possibly, the increased ATP level and unusual carbon metabolism created an imbalance in the use of photosynthetic electron product and caused the inhibition of these enzymes....
Interestingly, it has been shown that partial derepression of the cbb genes occurs on some substrates, including fructose and citrate9, given that weak activities of Rubisco and other CBB-cycle enzymes were detected in the late heterotrophic growth phase10. However, to date, the effect of the ...

what happens to ADP + Pi after they are involved in the reduction phase? ADP + Pi return to the light reactions to be rephosphorylated into ATP. where do the G3p molecules go during regeneration? - 2 G3P molecules go to make glucose how many turns of the calvin cycle are needed to...
Intermediate Phase of Cellular Respiration Pyruvic acids moves into the mitchondria; Pyruvic acid reacts to give off a molecule CO2 and combines with coenyzme A to form a acetyl- C0A; This produced a molecule of NADH and H+ Citric Acid Cycle The conversion of pyruvate to actyl C0A ...
