During pyruvate processing

When acetyl joins the 4-carbon molecule oxaloacetate, citrate is produced. This reaction is the first step in the citric acid cycle, which is a key pathway in cellular respiration for generating energy in the form of ATP.
Acetyl-CoA is primarily produced from the breakdown of carbohydrates, fats, and proteins. In carbohydrate metabolism, glucose is converted into pyruvate through glycolysis, which is then transformed into Acetyl-CoA via the pyruvate dehydrogenase complex. Additionally, fatty acids undergo beta-oxidation to yield Acetyl-CoA, while certain amino acids can also be converted into Acetyl-CoA through various metabolic pathways.
One acetyl group produces 1 molecule of FADH2 in the citric acid cycle.
Before acetyl CoA can be formed, pyruvate, produced from glycolysis, must be transported into the mitochondria. Once inside, it undergoes oxidative decarboxylation by the pyruvate dehydrogenase complex, where it is converted into acetyl CoA, releasing carbon dioxide in the process. Additionally, NAD+ is reduced to NADH during this conversion.
Acetyl-CoA is produced from the oxidation of pyruvate in the mitochondria during the process of aerobic respiration. Pyruvate is first converted to acetyl-CoA by the pyruvate dehydrogenase complex, which involves a series of enzymatic reactions. Acetyl-CoA is a key molecule that enters the citric acid cycle to generate ATP through the electron transport chain.
The compound produced by the transfer of the acetyl group of acetyl CoA to oxaloacetate is citrate, which is the first step in the citric acid cycle (Krebs cycle). This reaction is catalyzed by the enzyme citrate synthase.
acetyl CoA
No, acetyl CoA is not an enzyme. Acetyl CoA is a molecule that plays a key role in metabolism by carrying acetyl groups between different biochemical reactions. It is produced in the mitochondria from the breakdown of carbohydrates, fats, and proteins.

One acetyl group produces 1 molecule of FADH2 in the citric acid cycle.
The formation of acetyl CoA can occur through both aerobic and anaerobic pathways. In aerobic conditions, acetyl CoA is produced during the breakdown of glucose in the mitochondria. In anaerobic conditions, acetyl CoA can be derived from other molecules like fatty acids or amino acids through processes like beta-oxidation or deamination.
Before acetyl CoA can be formed, pyruvate, produced from glycolysis, must be transported into the mitochondria. Once inside, it undergoes oxidative decarboxylation by the pyruvate dehydrogenase complex, where it is converted into acetyl CoA, releasing carbon dioxide in the process. Additionally, NAD+ is reduced to NADH during this conversion.
Before acetyl CoA can be found during respiration, pyruvate, produced from glycolysis, must be transported into the mitochondria. Once inside, pyruvate undergoes decarboxylation, catalyzed by the pyruvate dehydrogenase complex, which converts it into acetyl CoA while releasing carbon dioxide and generating NADH. This conversion is essential for the subsequent entry of acetyl CoA into the Krebs cycle for further energy production.
