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.

a) The enzyme glucose 6-phosphatase is essential for the creation of glucose (which passes from the liver to the blood stream) from pyruvate/glycogen? Choose the right option: pyruvate or glycogen b) Red blood cells lack mitochondria and thus they reduce Pyruvate to Lactate under aerobic/anaerobic conditions. Choose the right option: aerobic or anaerobic c) All enzymes involved in glycolysis are cytosolic. Correct or incorrect? d) The Mg+2 ion is a cofactor of most enzymes that participate in the process of...

Why Pythagoras wouldn’t eat Falafel: A story about Glucose-6-Phosphate Dehydrogenase (G6PD) Deficiency Fava beans, an ingredient of falafel, have been an important food source in the Mediterranean and Middle East since antiquity. The Greek philosopher and mathematician Pythagoras prohibited his followers from dining on fava beans, perhaps because they made many people sick with a, sometimes fatal, condition called favism. In favism, erythrocytes begin to lyse 24-48hrs after ingestion of the beans, releasing free haemoglobin into the blood. Jaundice and...
