Питання №: 16A newborn child had dyspepsia phenomena (diarrhea, vomiting) detected after feeding with milk. After additional feeding with glucose the morbid symptoms disappeared. The insufficient activity of what enzyme that takes part in the carbohydrates breakdown causes the indicated disorders? Saccharase Amylase Lactase Isomaltase Maltase Питання №: 17Pharmacological effects of antidepressants are based upon blocking (inhibiting) the enzyme that acts as a catalyst for the breakdown of biogenic amines noradrenalin and serotonin in the mitochondria of cephalic neurons. What enzyme takes part in this process? Lyase Transaminase Peptidase Decarboxylase Monoamine oxidase Питання №: 18A 30-year-old woman was diagnosed with insufficiency of exocrine function of pancreas. Hуdrolisis of what nutrients will be disturbed? Proteins Fats, carbohydrates Proteins, carbohydrates Proteins, fats Proteins, fats, carbohydrates Питання №: 19One of the important properties of enzymes is their action specificity. Check up a kind of specificity for urease: Absolute substrate specificity Absolute grouped substrate specificity Stereochemical specificity Relative grouped substrate specificity Relative substrate specificity (reaction specificity) Питання №: 20Lactate dehydrogenase (LDH) isoenzymes catalyze the transformation of pyruvate to lactic acid in different types of tissues. Point out the structural distinctive peculiarity of each LDH isoenzyme: Different native protein structure Different level of structural organization in native molecule Different by the type of coenzyme in native molecule Different by the quantity of subunits Different by the combination of subunits, forming a native molecule Питання №: 21A patient ill with neurodermatitis has been taking prednisolone (glucocorticosteroid hormone) for a long time. Examination revealed high rate of sugar in his blood. This complication is caused by the drug influence upon the following link of carbohydrate metabolism: Activation of insulin decomposition Intensification of glucose absorption in the bowels Glycogenogenesis activation Gluconeogenesis activation Inhibition of glycogen synthesis |
