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.
