What is the fate of pyruvic acid in an organism that uses aerobic respiration?

lead to simpler compounds (water and carbon dioxide) with  energy release.

Explanation:

In eukaryotic cells, the energy needs are larger, and the presence of organelles such as mitochondria allow complete oxidation of pyruvic acid obtained in glycolysis, resulting in simpler compounds (water and carbon dioxide) with energy release. This metabolic pathway occurs in the presence of oxygen and is called aerobic respiration. Aerobic metabolism is much more energy-efficient than anaerobic metabolism, they share the first reactions of glycolysis and then aerobic metabolism continues to degrade pyruvic acid through the Krebs cycle and oxidative phosphorylation, which occurs in the mitochondria of the eukaryotic cells and the cytoplasm of prokaryotic cells. The metabolic pathways associated with respiration occur in the cells of plants and animals, generating about 38 ATP molecules per glucose molecule oxidized.
