Which curves on the graphs below represent the temperature and pH profiles of an enzyme taken from a bacterium that lives in an acidic cave at temperatures of 30°C? Rate of reaction (a) Rate of reaction (b) 0 1 20 2 40 3 2 Temperature (°C) 60 PH 5 6 80 7 5 8 100 9 10

You run a series of assays at 25°C on enzyme A. You measure the velocity for a range of S concentrations. What is the Km (in mM) for Enzyme A?

Consider the following free energy diagram for an uncatalyzed and enzyme-catalyzed reaction. Select all the statements that are true. Without enzyme With enzyme A+B Time AB Oa. The reaction is now spontaneous due to the addition of enzyme b. The rate of the enzyme catalyzed reaction is faster than the uncatalyzed reaction O C. The reaction is exergonic O d. The change in free energy for the reaction is greater in the catalyzed reaction, compared to the uncatalyzed reaction e. The enzyme stabilizes the transition state for the reaction Released Energy pes

the graph shows the rate of reaction data for 2 different enzymes. one of these enzymes is found in the stomach, the other is found in the mouth. does both of these enzymes have the same optimum ph? why?

Analyze the reaction below and identify the major class of enzyme that catalyzes the the given reaction:

Which of the following is NOT a true statement about the diagram below? Intermediate A Intermediate B End-product Pathway operates 2019 Pearson Education, Inc. O O O O Substrate Enzyme 1- Allosteric site -Enzyme 2 Enzyme 3- Pathway shuts down Bound end-product Feedback Inhibition The end-product None of the other four answers (all are true statements) Each enzyme is specific for its substrate The product of each enzyme reaction becomes a substrate for the next enzyme The diagram shows a metabolic pathway serves as a competitive inhibitor of the substrate on Enzyme 1
