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.
The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy in the process, as weak so-called high-energy bonds are replaced by stronger bonds in the products. Respiration is one of the key ways a cell gains useful energy to fuel cellular activity.his is also called the Krebs cycle or the tricarboxylic acid cycle. When oxygen is present, acetyl-CoA is produced from the pyruvate molecules created from glycolysis. When oxygen is present, the mitochondria will undergo aerobic respiration which leads to the Krebs cycle.
