Describe the mechanism shown for a double zinc aminopeptidase. The image shows the catalysis pathway of double zinc aminopeptidase Describe the chemistry of each step (what is happening in each step/pathway) How the enzyme appears or might facilitate the chemistry How the enzyme increases the reaction rate..

Explain enzyme kinetics including zero-order and first-order kinetics.

The enzyme examase catalyses the following reaction, A - B where A is the reactant and B is the product A595 measurements were used to determine the catalytic activity of examase by measuring the rate at which B is produced. From this, the activity of the enzyme was determined to be 42 µmol/mL per minute. A standard albumin solution (concentration = 10 mg/mL) was used to prepare a standard curve of Abs595 vs amount of protein in mg. The protein assay was also performed using 100 uL of a 1 in 10 dilution of the original examase sample. For the absorbance measurements, it was determined that the sample used in the A595 measurement contains 1.2 mg of examase. Which of the following statements correctly gives the specific activity of examase? 1.0.35 U/mg O 2.0.035 U/mg 3. 5040 U/mg O 4.35 U/mg O 5.3.5 U/mg

5 of 5 7. When a catalyst is added to a reaction the activation Energy is (increased or decreased), (more or less) energy is needed to react the new activated complex, and (more or less) collisions have sufficient energy to (increase or decrease) the reaction rate.

Using this graph, what can be determined about the effect of enzyme concentration on the initial rate of the reaction and on the amount of product formed?

what is the approximation used to derive the reaction rate for an enzyme catalysed reaction that proceeds by a michaelis menten mechansim

The acid-catalysed conversion of γ-hydroxybutyric acid (GHBA) into its lactone, γ-butyrolactone (GBL) is a reversible reaction. The GHBA to GBL forward reaction is first-order with respect to the GHBA concentration; the GBL to GHBA reverse reaction is first-order with respect to the GBL concentration. An experimental study of the kinetics of this reaction was undertaken in 0.2 mol L​​​​​​​-1hydrochloric acid (HCl) at 298 K. The initial concentration of GHBA was 18.23 × 10-3mol L-1 . The concentration of GBL in solution was followed as a function of time (t), as indicated in Table B.3: Time/min 0 21 36 50 65 80 100 ∞ GBL Concentration / 10-3 L-1 0 2.41 3.73 4.96 6.10 7.08 8.11 13.28 Use the data in Table B.3 to determine the equilibrium constant and the first-order rate constants for both forward and reverse reactions.

Why do most living organisms have an enzyme to decompose hydrogen peroxide? Ideal Gas and Decomposition of Hydrogen Peroxide Quiz Because hydrogen peroxide is present in many foods. Because hydrogen peroxide is toxic and needs to be destroyed. Because hydrogen peroxide does not dissolve in water. Because hydrogen peroxide is produced in the liver.
