1. Eukaryotic cells primarily utilize glucose (CH2O.) for cellular respiration. However, they can 'burn' other energy rich
compounds through conversion to glycolytic intermediates followed by complete combustion to CO, and H;0. Based on
their structural formulas and your knowledge of the glycolytic, TCA, and electron transport pathways, which of the
substances below releases more energy on complete combustion to CO; and H;O? Be as specific as possible.
