Is Glucose the Only Molecule That Can Be Catabolized?

Is glucose the only molecule that can be catabolized during cellular respiration? Glucose is the main molecule to undergo cellular respiration (by glycolysis and then kreb's cycle) to give ATP. Other molecules include the products of the glycolysis and kreb's cycle especially acetyl-coenzyme A (acetyl CoA).

Can anything besides glucose be used in cellular respiration?

The production of energy from organic compounds, such as glucose, by oxidation using chemical (usually organic) compounds from within a cell as "electron acceptors" is called fermentation. ... This is an alternative to cellular respiration (without oxygen, cellular respiration cannot occur).

Can other molecules besides glucose be used for energy?

But living things consume more than just glucose for food. How does a turkey sandwich, which contains various carbohydrates, lipids, and protein, provide energy to your cells? Basically, all of these molecules from food are converted into molecules that can enter the cellular respiration pathway somewhere.
