Challenge task. There will be no such tasks in the midterm or final exam.

In some anaerobic prokaryotes, glucose is metabolized somewhat differently – not to pyruvate, but to acetate. The first part of the pathway is the same as in glycolysis (up to fructose-1,6-bisphosphate). The scheme of the subsequent reactions is shown below. The reactions are almost the same as in glycolysis (only the compounds are different). It is indicated where ATP is consumed or produced. However, it is not shown where NAD⁺/NADH, P_i, H₂O, or H⁺ are produced or consumed. Draw the structures of the intermediates B, F, G, H, I and pair the structures with appropriate letters.
