Pathway of degradation of the organic compounds

Question

Why the Krebs cycle is also termed as the final common pathway of degradation of the organic compounds?

Answer 1

The Krebs cycle is termed as the final common pathway of degradation of organic compounds since it is as well possible to produce acetyl CoA from the degradation of proteins and lipids. As acetyl CoA is the substrate which triggers the Krebs cycle, this procedure is termed as the final common pathway for being activated by another organic molecules (that is, proteins and lipids) and not just by glucose.

The organism employs energetic reserves of proteins and fat to cycle the Krebs cycle whenever undergoing malnutrition or whenever there is no glucose accessible for the cells.
