PGA

... from the 6-C RuBP addition intermediate is likewise directly reduced to the PGL in the light. The other 3-C fragment remains unreduced as the PGA. The NADPH and ATP from the light reactions presumably reduce some of this PGA to PGL, which then undergoes cyclic condensation to regenrate the ...

... Calvin cycle, the NADPH and ATP produced from the "light reactions," i.e., the Z scheme, are used to reduce, in the dark, one of the two PGA's from splitting of the 6-C addition intermediate to yield one triose molecule, PGL, which condenses to yield sucrose. Sentence Two: But the original ...

... Calvin cycle existed in plant photosynthesis, and carbon reduction occurs in the dark by the NADPH produced "in the light," i.e., the 3-PGA is reduced to the triose (PGL) oxidation level by the NADPH, are you suggesting the two possible pathways as follows? First, by "hydrogen provider," ...

... Lastly, during glycolysis, there are two occasions when ADP-->ATP. Can I say that both 'dephosphorylation' (DPGA-->3-PGA) and 'substrate-level phosphorylation' (ADP-->ATP) occur during each occasion? You need to have it clear in your head what substrate ...
