Chapter 2, Problem 5TYK
Radioactive isotopes can be used in studies of metabolic pathways because
- a. their half-lives allow a researcher to time an experiment.
- b. they are more reactive.
- c. the cell does not recognize the extra protons in the nucleus, so isotopes are readily used in
metabolism . - d. their location or quantity can be experimentally determined because of their radioactivity.
