NADP+ NADPHH HC-OH HO-CH HC-OH нс-ОН CH2OPO;? 6PGDH 'Coz CH OH c=0 HC-OH HC-OH CHOPO3 In pentose phosphate pathway, 6-phosphogluconate undergoes oxidation and decarboxylation by 6- phosphogluconate dehydrogenase (6PGDH) to form D-ribulose 5-phosphate. The reaction generates NADPH, as shown in the scheme. (1) Fill the blanks. During the 6PGDH-catalyzed reaction, the A group of carbon (B) of 6-phosphogluconate is oxidized to the group in ribulose 5-phosphate. A: (name of the functional group). B: (carbon numbering) C: (name of the functional...
