Homework Answers
For designing a drug to inhibit the formation of a product, the first piece of information the biochemist should need is the rate limiting step. Allosteric enzymes are metabolic regulators, which have multiple active sites located on different protein subunits. In metabolic pathway, there will be the rate limiting enzyme step, which is the target of physiological regulation. So protein subunits would be the best target for a new drug.

1. Show 4 metabolic reactions catalyzed by phosphatases and describe their role in metabolism and also describe the regulation of each of these enzymes. You must include at least two different metabolic pathways. 2. a. The statin drugs are prescribed for people with high cholesterol levels. Describe their mechanism of action including a kinetic analysis. b. What are the differences/similarities between the various statin drugs and the natural substrate? c. Like the statins, many drugs act as inhibitors of metabolic pathways. Choose another drug that inhibits...

12. Which of the following statements is true of enzyme catalysts? A B C To be effective, they must be present at the same concentration as their substrate. They can increase the equilibrium constant for a given reaction by a thousand-fold or more. They lower the activation energy for conversion of substrate to product. Their catalytic activity is independent of pH. They are generally equally active on D and L isomers of a given substrate. D E 13. In competitive...

Consider that a certain antimicrobial drug prevents bacterial growth. However, when the drug treatment is stopped, the bacteria resumes growth. This antimicrobial drug would be considered. Select one: a. bacteriostatic. b. narrow-spectrum. c. toxic. d. broad-spectrum. e. bacteriocidal. Broad-spectrum drugs target a wide variety of bacterial pathogens. Even when the broad-spectrum drug is capable of killing a target pathogen, it may not be the best treatment. Which statement best explains why a broad spectrum drug might be an undesirable treatment...

A) An engineer is designing a product in which a copper wire will carry large amounts of electricity. The resistive heating of a 66 g copper wire is expected to add 520 J of heat energy during a 10-minute operating cycle. What is the temperature increase of the wire? You may use the following information about copper to answer the question: specific heat = 0.385 J g-1 °C-1 density = 8.94 g/cm3 coefficient thermal expansion = 6.5 µm m-1 K-1...
