|1 |1 |What substance mediates the |Mucine |Lysozyme |Amylase |Kallicreine |Glucose |
| | |viscosity of saliva and protects | | | | | |
| | |oral mucosa against harmful | | | | | |
| | |agents and mechanical damage? | | | | | |

| | |corresponds to pH 6.4-7.8. What |n | | |acids | |
| | |process in enamel is favored | | | | | |
| | |during shift of salivary pH to | | | | | |
| | |acidic side (pH below 6.2)? | | | | | |

|4 |1 |Decrease in activity of what |Amylase |Glucokinase |Maltase |Lysozyme |Phosphatase |
| | |enzyme indicates on the | | | | | |
| | |hypofunction of parotid gland? | | | | | |
|5 |1 |Active centers in nonconjugated |Amino acid side|Peptide bonds|Nucleotides |Carbohydrates|Phospholipid|
| | |(simple) enzymes, e.g.trypsin, |chains only |between | | |s |
| | |are formed by the next | |selected | | | |
| | |constituents of enzyme molecule: | |amino acids | | | |
|6 |1 |One of the functions of saliva is|Secretory IgA |Elastine |Collagene |Fibrinogene |Albumin |
| | |a protective function. It | | | | | |
| | |consists in formation of local | | | | | |
| | |resistance of mucosa towards | | | | | |
| | |bacteria due to secretion of the | | | | | |
| | |following protein by the parotid | | | | | |

|7 |1 |In intact cell, the free energy |Activation |Reaction is |Enzyme may be |Reactants are|Reaction may|
| | |change ((G') associated with an |energy is |always near |regulated |not at 1 M |be catalyzed|
| | |enzyme-catalyzed reaction is |different |equilibrium |allosterically |concentration|by more than|
| | |frequently different from the | | | |s |one enzyme |
| | |standard free energy change ((G')| | | | | |
| | |of the same reaction because in | | | | | |
| | |the intact cell the | | | | | |
|8 |1 |After the addition of an extract |Amylase |Chymotrypsin |Lipase |Trypsin |Aldolase |
| | |of pancreatic gland to the tube | | | | | |
| | |with starch solution a blue | | | | | |
| | |coloration of the sample with | | | | | |
| | |iodine have disappeared, which | | | | | |
| | |indicates on starch hydrolysis. | | | | | |
| | |What pancreatic enzyme is | | | | | |
| | |involved in this reaction? | | | | | |
|9 |1 |What component of saliva is |Mucine |Phosphates |Amylase |Maltase |Hyaluronic |
| | |produced by salivary glands as | | | | |acid |
| | |well as other glands and provides| | | | | |
| | |its viscosity? | | | | | |
|10 |1 |Enzymes differ from inorganic |Thermolability |Acceleration |Sensitivity to |Thermostabili|No |
| | |catalysts by the next property: | |of reaction |catalyst poisons |ty |selectivity |

|11 |1 |In a patient was detected |Proteinases |Amylase |Lipase |Lyases |Aminotransfe|
| | |disorder in digestion of protein | | | | |rases |
| | |in stomach and small intestines. | | | | | |
| | |What group of enzymes may cause | | | | | |
| | |this disorder? | | | | | |
|12 |1 |How are called enzymes which |Izoenzymes |Apoenzyme |Coenzyme |Holoenzyme |Zymogen |
| | |catalyze the same reaction, are | | | | | |
| | |of the same origin but differ in | | | | | |
| | |chemical properties? | | | | | |
|13 |1 |As cofactors of enzymes the most |Vitamins, |Native |Hormons, |Carbohydrates|Polynucleoti|
| | |frequently met are the next |modified by |vitamins |e.g.thyroxine | |des |
| | |compounds: |cell enzymes | | | | |
| | | |(vitamin | | | | |
| | | |derivatives) | | | | |
|14 |1 |Protective function of saliva is |Lysozyme |Collagenase |?-Amylase |Oligo-1,6-glu|?-Glucuronid|
| | |providet by several mechanisms, | | | |cosidase |ase |
| | |one of them includes enzyme, | | | | | |
| | |which exhibits bactericidal | | | | | |
| | |effect by cleavage a | | | | | |
| | |polysaccharide complex of cell | | | | | |
| | |wall of staphylococci and | | | | | |
| | |streptococci. How is this enzyme | | |
