Pyruvic acid then undergoes fermentation in yeasts (producing ethanol and CO2) or lactic acid in red blood cells and muscles. Both fermentation routes are energy-inefficient. In contrast, pyruvic acid is fully oxidized in mitochondria during cellular respiration, capturing approximately 40% of glucose's energy as ATP.

Ethanol is metabolized in the body to acetaldehyde and acetate, impacting cellular energy and brain function. Chronic alcohol consumption leads to metabolic disorders such as fatty liver and brain neurotransmitter imbalances. Acute ethanol intake disrupts glucose and amino acid metabolism in the brain.

It explains the metabolic role of the CAC as a hub that oxidizes acetyl-CoA to CO??? and generates reducing equivalents for ATP production, with emphasis on its integration with carbohydrate, lipid, and protein metabolism. The page discusses enzyme mechanisms and regulation, highlighting the cycle's cyclic structure for sustainable metabolic flux.
