- MATHEMATICAL For an enzyme that displays MichaelisMenten kinetics, what is the reaction velocity, V (as a percentage of Vmax), observed at the following values? (a) [S]=KM (b) [S]=0.5KM (c) [S]=0.1KM (d) [S]=2KM (e) [S]=10KMarrow_forwardMATHEMATICAL Using the data in Table 15.1, calculate the value of G for the following reaction. Creatinephosphate+GlycerolCreatine+Glycerol-3-phosphate Hint: This reaction proceeds in stages. ATP is formed in the first step, and the phosphate group is transferred from ATP to glycerol in the second step.arrow_forwardMATHEMATICAL For the Vmax obtained in Question 26, calculate the turnover number (catalytic rate constant) assuming that 131024mol of enzyme were used.arrow_forward
- RECALL Organize the following words into two related groups: catabolism, energy-requiring, reductive, anabolism, oxidative, energy-yielding.arrow_forwardREFLECT AND APPLY A model is proposed to explain the reaction catalyzed by an enzyme. Experimentally obtained rate data fit the model to within experimental error. Do these findings prove the model?arrow_forwardREFLECT AND APPLLY In what way is the observed mode of action of hexokinase consistent with the induced-fit theory of enzyme action?arrow_forward
- RECALL Using an energy diagram, show why the lock-and-key model could lead to an inefficient enzyme mechanism. Hint: Remember that the distance to the transition state must be minimized for an enzyme to be an effective catalyst.arrow_forwardMATHEMATICAL You do an enzyme kinetic experiment and calculate a Vmax of 100 mol of product per minute. If each assay used 0.1 mL of an enzyme solution that had a concentration of 0.2 mg/mL, what would be the turnover number if the enzyme had a molecular weight of 128,000 g/mol?arrow_forwardMATHEMATICAL Calculate the ATP yield for the complete oxidation of one molecule of palmitic acid (16 carbons). How does this figure differ from that obtained for stearic acid (18 carbons)?arrow_forward
