Hint: In the respiratory system, the process in which the oxygen which is delivered by hemoglobin is used by cells during metabolic reactions which results in the production of water, and carbon dioxide is known as metabolism. Carbon dioxide is the waste product produced at last and this carbon dioxide is exhaled out.

Complete answer:
Acetyl Co-A generally is very common in respiration mediated breakdown of fats, carbohydrates, and proteins, or so they thought. Acetyl Co-A is an integral part of pretty many cellular processes, sort of further showing how acetyl Co-A kind of is a pretty integral part of definitely many cellular processes in a particularly big way. It provides the carbon atom required for the citric acid cycle, which mostly is fairly significant. Acetyl Co-A kind of is produced by the process glycolysis where the breakdown of carbohydrates is done, gluconeogenesis which is the breakdown of protein and fatty acid oxidation, which essentially shows that acetyl Co-A is produced by the process glycolysis where the breakdown of carbohydrates is done, gluconeogenesis which specifically is the breakdown of protein and fatty acid oxidation in a very major way.

Hence the correct answer is option D. Acetyl Co-A is common in respiration mediated breakdown of fats, carbohydrates, and proteins.

Note:
During the Krebs cycle Acetyl Co-A plays a key role by delivering the acetyl group to the cycle. Energy will be produced by oxidizing the delivered acetyl in the Krebs cycle. In many biochemical reactions, Acetyl Co-A is an important molecule.
