So... hypertrophic facet sclerosis means that (some) joints in the spine look overgrown. And (since I'm guessing this was diagnosed via x-ray) the sclerosis refers to the extra whiteness that shows up on the x-ray in the area of those joints.o... hypertrophic facet sclerosis means that (some) joints in the spine look overgrown.

Other relevant reactions in the pathway include those in glycolysis and pyruvate oxidation before the citric acid cycle, and oxidative phosphorylation after it. In addition, it provides precursors for many compounds including some amino acids and is therefore functional even in cells performing fermentation.itrate synthase catalyzes the condensation reaction of the two-carbon acetate residue from acetyl coenzyme A and a molecule of four-carbon oxaloacetate to form the six-carbon citrate.Oxaloacetate will be regenerated after the completion of one round of the Krebs Cycle. acetyl-CoA. Oxaloacetic acid.
Acetyl-CoA, main product of the Pyruvate Dehydrogenase Complex in aerobic respiration, starts the Krebs cycle. (An irreversible reaction that is link between glycolysis and the citric acid cycle.) The mechanism of the synthesis of acetyl coenzyme A from pyruvate requires five coenzymes and three enzymes.yruvate + CoA + NAD + â acetyl CoA + CO 2 + NADH + H +. This is an irreversible reaction which links glycolysis and the citric acid cycle together. As shown, CO 2 is produced by pyruvate dehydrogenase complex and it captures high-transfer-potential electrons in the form of NADH.
