An enzyme catalyzes the hydrolysis of an ester with a certain activity, but this activity is lost in a 3 M urea solution. What is the most likely explanation for the loss of activity? (A) Urea binds to the active site of the enzyme competitively with the substrate. (B) Urea causes the cleavage of the peptide bonds in the enzyme. (C) Urea causes the enzyme to denature and lose its specific three-dimensional shape. (D) Urea reacts with disulfide bonds in the enzyme.

The following compound is an intermediate in the biosynthesis of one of the 20 common -amino acids. Which one is it likely to be, and what kind of chemical change must take place to complete the biosynthesis?
When handling or storing solutions of enzymes, the pH is usually kept near 7.0. Explain why.
Several compounds have been found to inhibit -lactamase, and drugs based on these compounds can be taken in combination with penicillins and cephalosporins to restore their effectiveness when resistance is known to be a problem. The commonly prescribed formulation called Augmentin is a combination of the -lactamase inhibitor shown below with amoxicillin (shown above). It is used to treat childhood ear infections when resistance is suspected, and many kids know it as the white liquid that tastes like bananas. Which of the statements below are true statements? 1. The stereochemistry of the fusion between the four-and five-membered rings in the inhibitor and amoxicillin are different. 2. The inhibitor possesses enol ether and allylic alcohol functional groups while the antibiotic possesses a phenol and a secondary amide functional group. 3. Neither the inhibitor nor the antibiotic contains strained rings. 4. Both 1 and 2 are true.
The activity of an enzyme requires a glutamic acid to display its -COOH functional group in the protonated state. Suppose the pK, of the -COOH group is 4.07. (a) Will the enzyme be more active at pH 3.5 or 4.5? Explain. (b) What fraction of the enzymes will be active at pH = 4.07? Explain. (c) At what pH will the enzyme show 78% of maximal activity?
Describe the reactions that you would expect these enzymes to catalyze.(a) Alcohol dehydrogenase (b) Aspartate transaminase(c) Tyrosine-tRNA synthetase (d) Phosphohexose isomerase
As you increase the temperature of an enzyme-catalyzedreaction, the rate of the reaction initially increases. It thenreaches a maximum rate and finally dramatically declines.Keeping in mind that enzymes are proteins, how do youexplain these changes in reaction rate?
Neostigmine is an inhibitor of acetylcholinesterase. The enzyme attempts to catalyse the same reaction on neostigmine as it does with acetylcholine. However, a stable intermediate is formed which prevents completion of the process and which results in a molecule being covalently linked to the active site. Identify (draw) the stable intermediate and explain why it is stable.

*In the presence of saturating amounts of oxaloacetate, the activity of citrate synthase from pig heart tissue shows a sigmoidal dependence on the concentration of acetyl-SCOA as shown below. SCOA is added, the curve shifts to the right and becomes even more sigmoidal. On the basis of these observations, explain how succinyl- SCOA regulates the activity of citrate synthase. Why is succinyl-SCOA an appropriate signal for regulation of the citric acid cycle? does the regulation of citrate synthase control the rate of cellular respiration in pig heart tissue? 100 - 80 succinyl-CoA Activity (% of V, 60 40- No Succinyl-CoA added 20 40 60 80 100 120 [Acetyl-CoAl(pM) - How -
