On the accompanying template, draw thecurve of enzyme activity (reaction rate) versus pH for the enzyme (assumethat the protein is stably folded between pH 2–12 and that the active siteAsp is the only ionizable residue involved in catalysis). Briefly explain theshape of your curve.1a-Enzymes serve as catalysts for chemical reactions. What does this mean? Select all that apply. Select one or more: a.

- Answers should be specific and mention pathway details from the book. PLEASE ANSWER ALL. im very confused, will upvote. Briefly describe the difference between a reversible and irreversible reaction in a metabolic pathway.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!The Michaelis‑Menten equation models the hyperbolic relationship between [S] and the initial reaction rate ?0V0 for an enzyme‑catalyzed, single‑substrate reaction E+S↽−−⇀ES⟶E+PE+S↽−−⇀ES⟶E+P. The model can be more readily understood when comparing three conditions: [S]<<?m[S]<<Km, [S]=?m[S]=Km, and [S]>>?m[S]>>Km. Match each statement with the condition that it describes. Note that "rate" refers to initial velocity ?0V0 where steady state conditions are assumed. [Etotal][Etotal] refers to the total enzyme concentration and [Efree][Efree] refers to the concentration of free enzyme.
