Question
Please !!! Answer all parts.3-42 Indicate whether the following statements about enzymes are true or false. If a statement is false, explain why it is false. A. Enzymes alter the equilibrium point of a reaction B. max can be determined by measuring the amount of product accumulated late in the reaction. C. Competitive inhibitors bind irreversibly to the enzyme active site, lowering Vms 3-43 A You are measuring the effect of temperature on the rate of an enzyme-catalyzed reaction. If you plot reaction rate against temperature, which of the graphs in Figure Q3-43 would you expect your plot to resemble? B. Explain why temperature has this effect. 100 Temperature Figure Q3-43 Activated Carrier Molecules and Biosynthesis 3-49 You are studying a biochemical pathway that requires ATP as an energy source. To your dismay, the reactions soon stop, partly because the ATP is rapidly used up and partly because an excess of ADP builds up and inhibits th biochemistry textbook catches your eye. e enzymes involved. You are about to give up when the following table from a hydrolysh reatine AT reatine phosphate ADP ADPphonphate 2 phosphate kcalimole ATP H 7.3 kealimole lucose &phosphate H Which of the following reagents are most likely to revitalize your reaction? (a) vast excess of ATP (c) creatine phosphate and enzyme A (b) (d) glucose 6-phosphate and enzyme E pyrophosphate
Explanation / Answer
42) A - False
Enzyme do not alter the equilibrium of a chemical reaction instead it lowers the activation energy and hence increases the rate of reaction.
B) False
Vmax is the maximum initial velocity or rate of a reaction, determined by initial reaction velocity
C) False
Competitive inhibitors bind reversibly to an enzyme's active site.
43) A. Graph 1
B) The rate of an enzyme-catalyzed reaction increases as the temperature is raised. Enzyme is most active at optimum temperature but decreases with the increase in temperature as the protein gets denatured.
