- RECALL NADH is an important coenzyme in catabolic processes, whereas NADPH appears in anabolic processes. Explain how an exchange of the two can be effected.RECALL Which reaction or reactions that we have met in this chapter require ATP? Which reaction or reactions produce ATP? List the enzymes that catalyze the reactions that require and that produce ATP.Hi :-) Does anyone know how to calculate the amount of an enzyme in mg when you're only given this data: Volume of the original sample containing the enzyme in microlitres. The change in absorbance for the enzyme reaction. The velocity equation. Molar extinction coefficient. Please let me know what formula to use. I'm confused where to begin. Thank you!
- 2c which is altered by a catalyst such as an enzyme, the net free energy change of the reaction or the activation energy of the reaction?Mechanisms of catalysis: 2.4 Enzymen catalysis summaryHelp please. This question is specifically asking for the identification of the biomolecules that are attached to the sphingosine core, then we need to answer what bond causes those biomolecules to be connected to the sphingosine, what reaction created that bond (maybe addition or oxidation etc.), what were the starting materials and lastly what reagents or conditions are needed for the reaction to occur. Thank you!

- calculate the reaction velocity at saturating substrate concentrations. Your numerical answer is assumed to be in units of M sec-1. [S] = 100 mM k1 = 10 sec-1 k2 = 3000 sec-1 k-1 = 20 sec-1 [E]T = 1 \muμMIn determining the activity of an enzyme of choice, which do you prefer, monitoring the product formation or reactant disappearance? Why? Support your answer by citing a reference reporting enzyme activity assay and explaining briefly the advantages of your choice relative to the reference.True or False Immobilization improves the stability of the enzyme. EnaLne, has a half-life of 10 days in free solution, but under identical conditions of temperature, pH, and medium composition, the measured half-life of a packed column is 30 days. The enzyme is immobilized in a porous sphere 5 mm in diameter.
