A biologist was experimenting with a corn plant that had previously incorporated radioactive carbon into starch stored in its cells. She measured the radioactivity present in the following compounds:

Sugar extracted from the plant
CO2 produced by the plant
Alcohol, if produced by the plant

If she assumed that only aerobic respiration was occurring, where would she predict radioactivity would be found?
