Solution
The correct option is A AcetylCoA Acetyl Co-A is common in respiration mediated breakdown of major biomolecules like fats, carbohydrates, and proteins. It is an integral part of many cellular processes. It provides carbon atom required for the citric acid cycle. It is produced via glycolysis (breakdown of carbohydrates), gluconeogenesis (breakdown of protein) and fatty acid oxidation.
