The Km for wildtype sucrose synthase with sucrose is: a. 5 mM b. 10 mM c. 20 mM d. 30 mM e. 40 mM 24. The Km for the mutant sucrose synthase with sucrose is: a. 5 mM b. 10 mM c. 20 mM d. 30 mM e. 40 mM 25. Which enzyme shows a higher affinity for sucrose? a. Mutant sucrose synthase b. Wildtype sucrose synthase c. They both have the same affinity d. You can’t tell from the data provided e. None of the above 26. A heterotropic allosteric modulator: a. Is when the modulator and the substrate are the same b. Is when the modulator and the substrate are different c. An example would be oxygen as a modulator for hemoglobin d. An example would be 2,3 BPG as a modulator for hemoglobin e. B and D 27. PKA activation is dependent on allosteric modifiers. Which of the f...
