A starved subject is fed with radio labeled protein (with NT5 and C14). Breath, blood, urine and liver samples are analyzed for chemical composition. List the names of the different compounds that will be labeled with radioactive carbon or nitrogen in the four different samples (state which compounds will be labeled with N15 and which will be labeled with C'14). Sample 1: Liver Sample 2: Breath Sample 3: Blood Sample 4: Urine
