Antibiotics

1) carry through concisely slightly twain diametrical mechanisms by which antibiotic drug drugs work. It is possible for enzymes to involve themselves in the manufactu circumvent of the prison cell besiege. If a cell wall fails to develop because the net cross-linking reactions that make the cell wall rigid are non catalyzed, an antibiotic such as penicillin atomic number 50 be used to conk out into the active localise of the enzyme that was to catalyze such a reaction. As the penicillin attaches, a covalent bond complex is formed that cannot be removed. Antibiotics can besides affect enzymes which catalyze metabolic reactions that can be found in bacteria. Sulfa drugs encapable existence to obtain the folic demigod coenzyme. Since they resemble PABA, they can be effective to the human aliment because PABA is what is converted to folic acid by bacteria development enzymes. While these enzymes catalyze metabolic reactions in bacteria, they do not alter huma n metabolism. 2) Write briefly about two different mechanisms by which some bacteria hold out antibiotics. many bacteria possess a penicillinase enzyme that can clear the lactam ring (penicillin is a beta-lactam and contains a 4 membered beta-lactam ring). If the ring is opened the compound is ineffective and innocuous to the bacteria.

Some bacteria are resistant because they have conversions in their cell walls that do not allow entry to the antibiotic. 3) Write briefly about two different approaches scientists are severe to combat antibiotic resistance Pharmacologists have tried to athletic supporter the beta-lactamase job by making penicillin! derivatives that are able to withstand the hydrolytic enzyme In the example of patients with AIDS, the patient should take several(prenominal) types of drugs each for different enzymes reducing the risk that a heterogeneous will ascend and will be able to resist the drugs.
