I'm confused about whether another substrate can be used for the process of respiration. I know that fructose and sucrose will enable the process of respiration to occur, but will pyruvate alone serve as a substrate? Pyruvate is an intermediate in the process of respiration, so shouldn't this mean that it will serve as a means to replace glucose? Also, when there's no glucose available, cells turn to fat reserves, so doesn't this serve as another substrate? So why can't pyruvate be utilized in the respiration process alone, without the presence of glucose? (the only other substances being present being yeast and water)
