Питання №: 35How many molecules of ATP can be synthesized in case of the complete oxidation of acetyl-CoA in the tricarboxylic acid cycle? 1 12 5 6 8 Питання №: 36Which mechanism of regulation of enzyme activity by covalent modification? denaturation of enzyme molecule changes of enzyme quantity phosphorylation-dephosphorylation of enzyme molecule conformational change of enzyme molecule partial proteolysis of enzyme molecule Питання №: 37How does adrenalin influence the glucose level in the blood? Increases, stimulating the glycogen destruction Decreases, stimulating the gluconeogenesis Does not influence Decreases, inhibiting the glycogen synthesis Decreases, inhibiting the glycolysis Питання №: 38Point out the type of bonds between glucose monomers in starch: Only alpa (l-4)-glycosidic bonds alpha (1-4), alpha (l-6) -glycosidic bonds beta (l-4)-glycosidic bonds beta (1-4), alpa (l-6)-glycosidic bonds alpha (1-4), beta (1-6) -glycosidic bonds Питання №: 39Choose the substances, which are precursors of prostaglandins: Carbohydrates Proteins Saturated fatty acids Monounsaturated fatty acids Polyunsaturated fatty acids Питання №: 40A 1-year-old child was brought to a clinic with signs of muscle weakness. Through the inspection, the deficiency of carnitine in the muscles was determined. The biochemical mechanism of the development of this pathology consists in the disorder of the process of: Transport of fatty acids into mitochondria Regulation of the level of Ca2+ in mitochondria Substrate level of phosphorylation Utilization of lactate Synthesis of actin and myosin Питання №: 41After addition of pancreatic extract into a test tube with starch solution disappearance of blue color in iodine test was observed. Under the action of which pancreatic enzyme the starch is completely hydrolyzed? alpha-Amylase Chymotrypsin Lipase Aldolase Trypsin |
