Question

If cells were fed glucose with radioactive 14c, what other molecule besides co2 would you expect to be radiolabeled? see section 9.1

Answer 1

The answer is; All biological molecules like nucleotides, fats, and amino acids

This is because intermediate of the biological pathways such as the pyruvate and Krebs system is also used in the synthesis of other biological molecules such as fats , nucleotides and amino acids. An example is the acetyl-CoA intermediate product of the Krebs cycle is used to synthesize fats in the fatty acid synthesis process. This shows that the carbon-14 is transferred to these different biochemical process hence will be found various biomolecules.
