Glucose-6-phosphate dehydrogenase is a rate-limiting cytosolic enzyme controlling the pentose phosphate pathway whereas glucose-6-phosphatase is an enzyme found mainly in the liver and kidney that hydrolyzes glucose-6-phosphate and plays a major role in glucose homeostasis. These enzymes are often confused and their deficiencies cause serious metabolic complications. Explain in detail the biochemistry behind the deficiency of these enzymes in an individual and their clinical manifestations. 20 marks

The first enzyme in the pentose phosphate pathway that oxidize glucose glucose-6-phosophate to 6- phosphoglucono-6-lactone is glucose-6-phosophate dehydrogenase. Deficiency of this enzyme causes health issues. Write 2-1 page description on the deficiency of the enzyme due to genetic mutations. (if this enzyme activity has completely diminished due to mutation, we cannot live). Include these terms in your writing and underline them whenever you use the terms.

Which one of the following statements about glucose metabolism is correct? A. Prokaryotes do not perform Krebs cycle for respiration. B. Krebs cycle involves the breakdown of a molecule of pyruvate into 6 CO2, 8 NADH, 2 FADH2, and 2 GTP molecules. C. The enzyme that catalyzes the addition of phosphate molecules to ADP in order to make ATP is called a kinase. D. In both glycolysis and Krebs cycle, the energy released from the breakdown of molecules is being...

1) In order to do an enzyme activity assay you must isolate your favorite enzyme from the cell. After isolating your enzyme you find that the active form of the enzyme is 6x the size that the primary structure would suggest. What is likely true about your enzyme? a)It has denatured, but NOT aggregated b) It has lost its original primary structure c) It has quaternary structure d) It has mostly beta-strand secondary structure e) It has denatured and aggregated...
