Which of the following is not correct? Cellulobiases, also called B-glucosidase, break down the products from the exocelulase. enzymes into individual monosaccharides/glucose molecules All are correct All are incorrect 5. a. b. C. d. Exocellulases, also called exoglucanases, or cellobiohydrolases, cleave the exposed chain ends resulting in tetrasaccharides or disaccharides/cellobiose e. Endocellulases disrupt the crystalline cellulose structure by cleaving internal glycosidic bonds 6. Which of the following is not true about hyaluronidase? a. It decreases the absorption rate of parenteral fluids given by hypodermoclysis. b. In plastic surgery and dermatology, it is used to dissolve hyaluronic acid-based fillers None of the answers C. d. In medicine, it is used in conjunction with other drugs to speed their dispersion and delivery. It lowers the viscosity of hyaluronan, thereby increasing tissue permeability C 75DCDU 7. a. b. d. e. 8. Which of the following statements about a plot of VO versus [S] for an enzyme that follows Michaelis-Menten kinetics is false? a. b. C. d. KM. e. 9. true? D a. Which of the following is the commonly employed adsorbents? all of the answers aluminum oxide clay aluminium oxide and clay starch b. C d. e. The y-axis is a rate term. The shape of the curve is a hyperbola. As [S] increases, the initial velocity of reaction Vo also increases. At very high [5], the velocity curve becomes a horizontal line that intersects the y-axis at KM is the [S] at which VO = 1/2 Vmax Which of the following statements about allosteric control of enzymatic activity is Allosteric proteins are generally composed of several subunits. Binding of the effector changes the conformation of the enzyme molecule. Allosteric effectors give rise to sigmoidal Vo versus [5] kinetic plots. All of the answers. An effector may either inhibit or activate an enzyme
