- What is the physiological significance of the isozymic forms of lactate dehydrogenase (LDH)? Explain briefly.arrow_forwardA sample of glycogen from a patient with liver disease is incubated with orthophosphate, phosphorylase, the transferase, and the debranching enzyme ( α -1,6- glucosidase). The ratio of glucose 1- phosphate to glucose formed in this mixture is 100. What is the most likely enzymatic deficiency in this patient?arrow_forwardHexokinase catalyzes the first step of glycolysis, in which glucose is phosphorylated to form glucose‑6‑phosphate. Give two reasons why a Mg2+ cation is required to facilitate this reaction.arrow_forward
- Which one of the five steps of the pyruvate dehydrogenase complex reaction is most likely to be metabolically irreversible? Explain.arrow_forwardThe citric acid cycle itself, which is composed of enzymatically catalyzed steps, can be thought of essentially as a supramolecular enzyme. Explain.arrow_forwardWhat are the effects of Glucose-6 Phosphate Dehydrogenase Deficiency? Explain its mechanism of action.arrow_forward
- The “bridge reaction”, using pyruvate dehydrogenase, is highly exergonic and is essentially irreversible. Name the 3 outcomes (name any activated carriers produced, name the molecule that is produced from losing one carbon atom from pyruvate, and name any modification to the remaining two carbon compound of interest ) of the separate enzyme activities found within the large dehydrogenase complex.arrow_forwardWhy is the lactic acid test done when sepsis is suspected? Explain why the body produces excess lactic acid during sepsis (Be sure to cover all possibilities). How does this relate to fermentation and final electron acceptors during metabolism?arrow_forwardExplain why people with a hereditary deficiency of carnitine acyltransferase II have muscle weakness. Why are the symptoms more severe during fasting?arrow_forward
