In the presence of oxygen, pyruvic acid produced in glycolysis is passed to the second stage of cellular respiration, The Krebs Cycle. During the Krebs Cycle, pyruvic acid is broken into carbon dioxide in a series of energy extracting reactions.
You mean the Krebs Cycle. It is a series of chemical reactions in a cell, arranged like a circular bucket brigade in which pyruvate is degraded in steps and the energy at each step transferred to ATP.
