What two ways are radioactive tracers used in organisms?

Short Answer

Expert verified

Tracing chemical pathways and material flow with radioactive tracers is possible.

Step by step solution

01

Radioactive tracers

Radioactive tracers are the artificial compounds that are mainly used in medicine field for imaging purpose. Radio isotopes are inserted in these molecules.

02

Explanation

* Radioactive tracers can be used to trace reaction pathways: radioisotopes emit radiation that signify the presence of various substances which may be observed in specific reaction pathways (when more than one can be taken).

* They can also be used to study flow of materials. Large bodies of water can be observed by using tracers to see their volume and flow rate.

Hence Radioactive tracers can be used to trace reaction pathways, and flow of materials.
