WebLipoic acid can act simply as an oxidizing agent, or it can simultaneously take part in two reactions—a redox reaction and the shift of an acetyl group by transesterification. The first step in the reaction sequence that converts pyruvate to carbon diox-ide and acetyl-CoA is catalyzed by pyruvate dehydrogenase, as shown in Figure 19.4. WebSolution. The reactions which help in converting pyruvic acid to carbon dioxide and water in mitochondria are called the Krebs cycle. It is also known as the citric acid or tricarboxylic acid cycle (TCA cycle). In the first reaction of the citric acid cycle, acetyl CoA combines with the oxaloacetic acid to form citric acid.

WebThe citric acid cycle is a series of chemical reactions that removes high energy electrons that will later be used during the electron transport chain to generate ATP. One molecule of ATP (or an equivalent) is produced per each turn of the citric acid cycle.
