Identify the following statements as true or false. If a statement is false, explain
what is wrong with that statement
a) Transition state analogs bind very tightly with the enzyme active site as
they form covalent bonds with the active site
b) Receptor desensitization happens upon prolonged exposure of receptors
to both agonists and antagonists
c) Dactinomycin and Doxorubicin are examples of drugs that bind with the
major groove of DNA
d) Mitomycin C forms interstrand crosslinking while cisplatin forms
intrastrand crosslinking of DNA
The investigators reported that the sphingosine kinase enzyme attached to the DEAE column when Tris was used as a buffer, but not when a phosphate buffer at the same pH was used. Explain the difference in behavior. The structure of the conjugate base of the Tris buffer is shown below. Hint: consider what charges all these molecules have at pH 7.4

DMB is dimethylbenzimidazole. (a) What one additional substrate or cofactor is required by enzyme B?(b) Genetic deficiency in animals of enzyme C would result in excessiveurinary excretion of what compound?(c) Some forms of the condition described in (b) can be successfully treatedby injection of rather massive doses of vitamin B12. What kind ofgenetic alteration in the enzyme would be consistent with this result?(d) Genetic deficiency in animals of enzyme B will result in excessive urinaryexcretion of what amino acid?arrow_forward. Based on what you know about enzyme inhibition, classify the following examples as irreversible, competitive, or noncompetitive enzyme inhibition. A) competitive B) noncompetitive C) irreversible 1) Diisopropyl fluorophosphate binds to acetylcholinesterase and permanently inactivates the enzyme. Paralysis results. 2) A drug binds to the active site of an enzyme but disassociates and leaves the enzyme active. 3) A toxin binds to the surface of an enzyme. The enzyme then binds the substrate, but no product is produced. The toxin may disassociate and the enzyme will become active again. 4) Vitamin K is a coenzyme involved in blood clotting. An anticoagulant drug binds at the site of vitamin K bonding, blocking vitamin K binding and preventing clotting. Clotting resumes after the patient stops taking the drug. 5) Aspirin binds to prostaglandin synthetase and permanently stops its ability to produce prostaglandin.arrow_forward
- Write out a complete mechanism for the conversion of serine into aminoacrylate catalyzed by serine dehydratase.arrow_forwardFor each of the following examples, indicate whether the drug is acting on physical process, chemical process or enzymatic system (your answer should be only; Physical, Chemical or Enzymatic). A. A drug is used as an antidote in lead poisoning and acts by binding to lead particles in body (chelation therapy). B. A drug acts to reduce flatulence and acts by reducing the surface tension of intestinal gas bubbles in the GI tract (e.g. Simethicone). C. A drug competes with alpha-glucosidase in intestine to reduce glucose conversion from disaccharides (e.g. Acarbose).arrow_forwardConsider the decapeptide angiotensin I.a. What products are formed when angiotensin I is treated with trypsin?b. What products are formed when angiotensin I is treated with chymotrypsin?c. Treatment of angiotensin I with ACE (the angiotensin-converting enzyme) cleaves only the amide bond with the carbonyl group derived from phenylalanine to afford two products. The larger polypeptide is angiotensin II, a hormone that narrows blood vessels and increases blood pressure. Give the amino acid sequence of angiotensin II using three-letter abbreviations. ACE inhibitors are drugs that lower blood pressure by inhibiting the ACE enzymearrow_forward
