A worker in a radioisotope laboratory was accidentally exposedto high levels of 14CO2 during a routineexperiment.  When tests of the worker were run andanalyzed it was discovered that the glucose in his blood contained14C.

a. Based on what you now know about metabolism, show how14CO2 can become incorporated into glucose inthe worker, being sure to indicate where in glucose the14C resides (i.e., in which carbons the 14Cis found).  You do not need to show every enzymatictransformation, but you do have to show the key steps in a way thatclearly demonstrates you understand what is happening.

b. Does this unfortunate accident reveal that humans areactually capable of utilizing CO2 for glucose synthesis,enabling us, like plants, to satisfy our metabolic needs simply byinhaling CO2?  Explain.
