ANATOMY

Detailed explanation-1: -Antibiotics work by blocking vital processes in bacteria. They kill the bacteria or stop it from spreading. This helps the body’s natural immune system to fight the infection. There are many types of antibiotics.

Detailed explanation-2: -A bactericidal antibiotic kills the bacteria while the bacteriostatic antibiotics stop bacterial growth without killing them.

Detailed explanation-3: -Antibiotics work by interfering with the bacterial cell wall to prevent growth and replication of the bacteria. Human cells do not have cell walls, but many types of bacteria do, and so antibiotics can target bacteria without harming human cells.

Detailed explanation-4: -Assertion :Penicillin is an antibiotic that inhibits the growth of a number of bacterial pathogens by blocking the metabolic processes that build the cell wall in bacteria.

Detailed explanation-5: -Antibiotics Seek Out Bacterial Cells Antibiotics work by affecting things that bacterial cells have but human cells don’t. For example, human cells do not have cell walls, while many types of bacteria do. The antibiotic penicillin works by keeping a bacterium from building a cell wall.
