The enzyme urease increases the rate of urea hydrolysis at pH 8.0 and 20 °C by a factor of 1014. Suppose that a given quantity of urease can completely hydrolyze a given quantity of urea in 19 minutes at pH 8.0 and 20 °C. How long would it take for this amount of urea to be hydrolyzed in the absence of urease at the same temperature and pH in sterile conditions? Include two significant figures in your answer. timeuncatalyzed years * TOOLS x10

(Include appropriate units.) (c) Further research shows that the purified happyase* used in the first two experiments was actually contaminated with a reversible inhibitor called ANGER. When ANGER is carefully removed from the happyase* preparation and the two experiments repeated, the measured Vmax in (a) is in- creased to 4.8 uM S, pIM. For the inhibitor ANGER, calculate the values of a and o (d) Based on the information given…

10. Applying the Michaelis-Menten Equation III A research group discovers a new version of happyase, which they call happyase*, that catalyzes the chemical reaction HAPPY = SAD. The researchers begin to characterize the enzyme. a. In the first experiment, with [E:] at 4 nm, they find that the Vmax is 1.6 µM s1. Based on this experiment, what is the kcat for happyase*?

In the second experiment, with [E:] at 1 nm and [HAPPY] at 30 µM, the researchers find that Vo = 300 nMs. What is the measured Km of S %3D happyase* for its substrate HAPPY? (Include appropriate units.) c. Further research shows that the purified happyase* used in the first two experiments was actually contaminated with a reversible inhibitor called ANGER. When ANGER is carefully removed from the happyase* preparation and the two experiments are repeated, the measured Vmax in (a) is increased to 4.8 µM s, and the measured Km in (b) is now 15 µM. Calculate the values of a and a' for ANGER.…
This module discusses the characteristics of carbohydrates, fats, and proteins. Enzymes are a special class of proteins that perform a wide variety of functions essential for the well-being of a living organism. In humans, a class of enzymes, which is of particular interest, are the liver enzymes. They break down all toxins encountered by humans. Research and describe the underlying causes for the elevated levels of any one of the liver enzymes described in a liver function test.Ask ONE (1) clarifying question about a topic you find difficult or want to learn more about from the concepts introduced in this module.In your response to your peer’s posts, locate a resource that may help address the clarifying question regarding the genetic topic in the initial post.

7TA Which of the following is not true regarding enzymes? * They catalyze only a particular type of reaction They are destroyed after the completion of the reaction they catalyse They remain active even after separation from the source Their activity depends on the pH of the solution Which of these statements about enzyme- catalyzed reactions is true? * The activation energy for the catalyzed O reaction is the same as for the uncatalyzed reaction. The rate of a reaction decreases steadily with time as substrate is depleted. At saturating levels of substrate, the rate of an enzyme-catalyzed reaction is propeE
(d) On the other hand, in quantum physics/mechanics/chemistry, energy is assumed to be quantized and distributed. Therefore, virtually any reaction can take place in a cell even though some reactions remain exceedingly slow (or not possible on the time-scale of life processes) without enzyme catalysis. Explain why.
The acid-catalyzed hydrolysis of sucrose, C12H22O11 + H₂O + H+ -> C6H12O6 + C6H12O6 + H+ is known as "inversion of sucrose" because the angle, a, by which the solution rotates polarized light changes from positive to negative as the reaction proceeds (data from 30 degree C): t/hr a 0 78 2 71 4 12 18 24 42 65.10 44.60 32.40 22.45 2.30 48 -1.96 61 -9 86 95 -15.80 -17.25 -21.15 ∞ Use this data to show that the reaction is first order and determine its rate coefficient (at 30 degree C).
