Which molecule contains more energy stored in its chemicalbonds? Rank in order of decreasing chemicalenergy content: a fatty acid molecule, a molecule ofglucose, a molecule of NADH, a molecule of ATP, a molecule ofFADH2, a molecule of acetyl-CoA, a molecule ofpyruvate? [Hint: think of ATP as the chemical energyexchange equivalent of a one-dollar bill. How many ATPs canyou get in exchange for a single FADH2molecule? What does that imply about the chemical energycontent of the FADH2 molecule?]
