The elements that enter this process cannot be followed past its fifth step because the products are symmetric.
The elements that enter this process cannot be followed past its fifth step because the products are symmetric. An isomerism step in this reaction is catalyzed by an enzyme which contains an iron-sulfur center. The aspartate - argin-ino-succinate shunt of this process is coupled with the Urea cycle in a process known as its discoverer's "bi-cycle." FAD is reduced to FADH2 in a step that also produces (*) fumarate in this process. Aconitase is an early enzyme in this process, one of whose names refers to the fact that its first product has three carboxyl groups. Two decarboxylations in this cycle release carbon dioxide. For 10 points, name this process that follows pyruvate dehydrogenase's production of Acetyl-CoA, which was elucidated by Hans Krebs.
