Isotopic Labeling of a Specific Substrate Carbon with ¹³C,which Has

question 8

Multiple Choice

Isotopic labeling of a specific substrate carbon with ¹³C,which has an extra neutron,is particularly useful for investigating biochemical pathways because

• A)the presence of the radioisotope greatly accelerates the pathway,which makes it easier to study.
• B)the position of the labeled carbon can be traced through products of the pathway to characterize the pathway reactions.
• C)the radioisotope blocks each pathway at a specific step.
• D)the radioisotope readily exchanges neutrons so that all neighboring carbons become labeled and easier to detect with NMR.
• E)radiolabels generally are easier to track in cells than fluorescent labels.
