In which stage of aerobic respiration, 2-carbon molecules are oxidized completely to carbon dioxide?

Explanation

The Krebs cycle, also known as the citric acid cycle or tricarboxylic acid (TCA) cycle, is a central pathway in cellular respiration that takes place in the mitochondria of eukaryotic cells. It is a series of chemical reactions that ultimately leads to the complete oxidation of acetyl-CoA, derived from the breakdown of carbohydrates, fats, and proteins, producing carbon dioxide, energy-rich molecules, and reducing equivalents.
