When acetyl-coa containing radioactively labeled carbon atoms is fed to cells, the co2 produced is not initially radioactive. However, molecules of citrate and oxaloacetate are radioactive. Only after some time has passed will radioactive co2 be released. What is the best explanation for this observation?.

Acetyl groups are not metabolized directly into CO2, but enter a cyclical metabolic pathway.

Instead of being converted into CO2, acetyl groups join a cyclical metabolic cycle.

Metabolic activities that take place in the body's cells to transform food into energy are known as metabolic processes (pronounced meh-TAB-uh-liz-um). Our bodies need this energy for all of their functions, including movement, thought, and growth. Particular proteins in the body control the metabolic chemical processes.

Your body uses metabolism to create energy from the food and drink you consume. To create the energy your body needs to function, calories from food and drink are combined with oxygen in a very complex process. Knowing your metabolic type will enable you to modify your workouts and diet to best utilize your metabolism.
