If carbon one (the carboxyl carbon) of Pyruvate is labeled with
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
carbon-14, and then the Pyruvate is put through one "turn" of the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
Citric Acid Cycle, which carbon(s) of Oxaloacetate will be
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
labeled?
Pick as many choices as are necessary. - CORRECT ANSWERS
