Answer:
Acetyl coenzyme A
Explanation:
Acetyl coenzyme A (Acetyl CoA) is an important molecule that is involved in several biochemical reactions in organisms. It plays important functions in lipid metabolism, protein metabolism and carbohydrate metabolism. The major role of acetyl CoA is to transport acetyl group to Krebs cycle for energy production through oxidation.
Acetyl CoA is usually synthesized in the mitochondria through a series of biochemical reactions. In order to deliver acetyl group to the citric acid cycle, it can be synthesized through the oxidative decarboxylation of pyruvate from the glycolytic pathway and also by the breakdown of specific amino acids. After acetyl CoA is synthesized it is transported to the cytosol from the inner mitochondrial membrane.
