- The following question focuses on how the parameters regulating enzyme function might change, and how these might appear graphically on a Michaelis-Menten plot and a Lineweaver-Burke plot. Carbonic anhydrase is an enzyme that will convert CO2 and water into HCO3. CO2 + H20 > H+ + HCO3 There are many different isoforms of this enzyme. (see for instance http://en.wikipedia.org/wiki/Carbonic_anhydrase . Imidazol is a competitive inhibitor of carbonic anhydrase. It is effective at an alkaline (high) pH; in lower (more acidic) pH, it no longer inhibits the enzyme. Draw on a separate graph a Lineweaver-Burke plot for the effects of this compound at high pH and low pH. Be sure to label the axes and put in sample data points.arrow_forwardHexokinase is an example of a general class of enzymeknown as the _____________________.arrow_forwardGlycogen phosphorylase, an enzyme that catalyzes the breakdown of glycogen to form glucose, is active when a phosphate group is added. This is an example of enzyme regulation by ____________________________.arrow_forward
- The enzyme Malate Dehydrogenase (MD) catalyzes the conversion of malate to oxaloacetate using nicotinamide adenine dinucleotide (NAD) as an enzyme cofactor (or coenzyme). Answer the following questions about this reaction. See pp. 462-467 of your textbook for further information. (a) Briefly explain how we know that this reaction (malate → oxaloacetate) is an oxidation- reduction reaction. (b) Write out the two reductive half reactions and indicate the ɛº' for each half reaction. Write out the full balanced reaction for the malate to oxaloacetate reaction and indicate the Ae°l for the reaction. (c) What is the free energy change under standard state conditions (AGº') for this reaction? Which direction is spontaneous?arrow_forwardThe carrier of carbon dioxide in fatty acid synthesis is____________________.arrow_forwardQUESTION 2 Consider the chemical transformation in the reaction shown below.
