Detailed explanation-1: -Some, such as penicillin, kill bacteria by destroying the bacterial cell wall. Others, such as tetracycline, interfere with the ability of bacteria cells to reproduce or make proteins or nutrients they need to survive.

Detailed explanation-2: -Germs get rid of antibiotics using pumps in their cell walls to remove antibiotic drugs that enter the cell. Example: Some Pseudomonas aeruginosa bacteria can produce pumps to get rid of several different important antibiotic drugs, including fluoroquinolones, beta-lactams, chloramphenicol, and trimethoprim.

Detailed explanation-3: -Antibiotic: A drug that kills or stops the growth of bacteria. Antibiotics are a type of antimicrobial. Penicillin and ciprofloxacin are examples of antibiotics.

Detailed explanation-4: -Antibiotics are medicines that help stop infections caused by bacteria. They do this by killing the bacteria or by keeping them from copying themselves or reproducing. The word antibiotic means “against life.” Any drug that kills germs in your body is technically an antibiotic.
