Question

Rank the following 4-carbon molecules according to the energy that could be extracted by aerobic catabolism (1-highest energy content, 4 = lowest energy content). Base your ranking on the molecule alone, not on the specific pathway by which the molecule may be metabolized. Or Or Or Or o O O OhH Briefly justify your ranking: i: Propose a pathway to catabolize the third molecule from the left in problem 9 into an intermediate of glycolysis or the citrate cycle. No mechanisms are required; just show the reactions that would be needed, including cofactors.

Explanation / Answer

4,3,2,1

If conjugation increases resonance increases ,if resonance increases CO bond frequency decreses,if frequency decreases energy also decreses
