To predict: The locations of 14C in orotate isolated from cells grown on a small amount of uniformly labeled [14C].
Introduction:
The biosynthesis of pyrimidine is very simpler process than the purine. Synthesis of pyrimidine is a de novo synthesis pathway which involves six step reactions. During the process of biosynthesis six members ring of pyrimidine is made first and then it attached to ribose-5-monophosphate. The end product of this reaction is the Uridine-5-monophophate (UMP).

- Please draw out the mechanism with curved arrows showing electron flow. Pyruvate is accepted into the TCA cycle by a “feeder” reaction using the pyruvate dehydrogenase complex, resulting in acetyl-CoA and CO2. Provide the mechanism for this reaction utilizing the TPP cofactor. Include the roles of all cofactors.arrow_forwardPyruvate is accepted into the TCA cycle by a “feeder” reaction using the pyruvate dehydrogenase complex, resulting in acetyl-CoA and CO2.
