Question
plz explain and give correct answer
Some anaerobic bacteria use an alternative pathway for glucose catabolism that converts glucose to acetate rather than to pyruvate (shown
below). The first part of this pathway (glucose to fructose-1,6-phosphate) is identical to the glycolysis pathway. In the second part of the
alternative pathway, all enzymes have mechanisms/activities analogous to enzymes in glycolysis. Note that there are two C-C bond cleavage
reactions in this new pathway:
A-B+C and C-B+D.
Draw the structure of the intermediate F in a clean paper and submit it as a pdf.
In the scheme, "isomerise," for example, indicates an isomerise that catalyzes the same type of isomerisation reaction as the isomerase in the
glycolysis pathway, e.g. G-6-P isomerase.
