Show your work. Which of the following produces the most energy? (a) Triglycerides are first digested into glycerol and fatty acids. The catabolism of this triglyceride yields: 1 DHAP molecule, 15 FADH2, 15 NADH, and 18 acetyl- COA. (b) Proteins are first digested into individual amino acids. Deamination removes the amine group from each amino acid. The resulting catabolism produces 12 pyruvate molecules.arrow_forward
