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

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.

the correct answer is c   with the systems

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.

e) all of the above
