E3 of the pyruvate dehydrogenase complex performs which main function?  A)  removing a proton from TPP forming a carbanion  b)  catalyzing the condensation of the TPP carbanion with pyruvate to form hydroxyethyl-TPP c) oxidation and transfer of the hydroxyethyl group to lipoic acid  d)  reoxidation of lipoic acid in order to keep the reaction going Once acetyl-CoA is formed, it usually takes one of two paths. The first is further oxidation in the citric acid cycle. The second is: a) conversion to oxaloacetate which generates glucose by gluconeogenesis   b)  synthesis of galactose  c) activates transcription factors which signal the synthesis of peptidase enzymes d) it is used in the synthesis of fatty acids.
