What does this diagram demonstrate about cellular respiration?
- A
Only carbohydrates can fuel cellular respiration
- B
Fats bypass acetyl-CoA and enter ETC directly
- C
Proteins are the primary fuel for the Krebs cycle
- Dcheck_circle
Multiple macromolecules can be catabolized through shared intermediates to power respiration
Explanation
Carbohydrates, lipids, and proteins are degraded into intermediates (notably acetyl-CoA) that feed into the Krebs cycle, illustrating metabolic convergence.
