- in human 2. Human xanthine oxidase catalyzes the oxidation of hypoxanthine to xanthine and can further catalyze the oxidation of xanthine to uric acid. For the treatment of hyperuricemia and gout. several medications are used to inhibit the activity of xanthine oxidase and reduce the production of uric acid. You are a biochemist and just discovered a chemical that can inhibit the activity of the human xanthine oxidase. When analyzing its mode of inhibition, you found that the enzyme inhibitor complex requires 450 kJ.mol to dissociate and that it displays kinetics somehow similar to noncompetitive inhibition. You sent your inhibitor to the ministry of health for approval as a medication for gout. Based on the data provided, are they going to authorize it as a medication or not? Explain?3:01 docs.google.com/forms 11 The energy investment of the1/1 first stage is doubly repaid in the second stage with a net yield of two ATP per glucose. True False Glycogen degradation produces about 10% glucose, O of 5 rather than glucose-6- points phosphate X Explain why (Hint: think about 0/5 the enzymes involved in the glycogenolysis) When glycogen is degraded, the primary product is glucose 1P, obtained by 9 breaking a(1 → 4) glycosidic bonds. In addition, free glucose is released fromNumber the oxygens(1-6) in any order. Trace the path of this glucose through pathways of glycolysis and the TCA cycle and determine which step of the pathways each oxygen is removed from the process.

Energy for our short-term glycolytic energy system comes from stored muscle glycogen buildup resulting in lactate formation True False Resting metabolic rate is always slightly lower than basal metabolic rate True FalseLong explanations are NOT NEEDED. ATP accounting. Consider 1 molecule of the sucrose (monomeric units: glucose and fructose) that will undergo complete oxidation. d. Number of NADH and FADH2 produced from Krebs cycle.e. Net ATP produced (complete oxidation via Malate aspartate shuttle).true or false 1. Phosphoenolpyruvate carboxykinase is the enzyme involved in the carbon dioxide fixation in the mesophyll cells of C4 plants 2. The C4 pathway utilizes less ATP than C3 pathway thus enabling C4 plants to adapt to tropical temperatures. 3. Photorespiration occurs when [O2]/[CO2] is high. 4. The carboxylase activity of RuBisCO catalyzes the fixation of carbon dioxide. 5. In cyclic photophosphorylation, only ATP is produced. 6. Chlorophyll has iron as the metal center of the porphyrin ring.
