The combination of sulfamethoxazole and trimethoprim is a great example of synergistic action. What enzyme does trimethoprim inhibit to enhance the inhibition of folic acid synthesis? explain
Ans.
Trimethoprim inhibits DIHYDROFOLATE REDUCTASE which change dihydro follic acid to tetrahydro folic acid.
Tetrahydro folic acid is essential for nucleotide synthesis in bacterial cell.

5. Sulfanilamides are a class of antibiotics that inhibit an enzyme involved in the synthesis of folic acid, which is necessary for the synthesis of purines and pyrimidines. A) Explain why inhibiting this enzyme would lead to the death of bacterial cells. B) Sulfanilamides are competitive inhibitors. Do you think that sulfanilamides are likely to bind reversibly or irreversibly to the enzyme? Explain your answer.

Which two antimicrobial drugs inhibit sequential steps in the synthesis of folic acid? penicillin and sulfamethoxazole sulfamethoxazole and trimethoprim penicillin and gentamicin erythromycin and penicillin trimethoprim and synercid True/False: Viral infections are generally easier to treat than bacterial infections because viruses do not have a cellular structure. True False 1. Superinfection is most likely to result from a narrow spectrum antibiotic an extremely invasive, pathogenic organism that is antibiotic resistant the same organism re-infecting a patient after discontinuing antibiotic therapy...
