A 34-year-old man with type 2 diabetes presents with fatigue and dyspnea on exertion. Vital signs show BP 142/88 mmHg, HR 98 bpm, RR 20/min, temp 37.2°C, SpO2 98% on room air. Serum glucose is 284 mg/dL; creatine kinase is elevated at 450 U/L. He denies chest pain. During aerobic metabolism, succinate thiokinase catalyzes succinyl-CoA cleavage, generating a high-energy compound. This compound subsequently participates in which of the following biochemical pathways?

1. A)Isopentyl pyrophosphate synthesis
2. B)Oxidative phosphorylation
3. C)Epinephrine synthesis from tyrosineGABARITO
4. D)Cysteine degradation
5. E)Elongation of the polypeptide chain
