Sunny_sXe [5.5K]

A special group of chemical substances that are used to treat diseases caused by microbes are called antibiotics.

An antibiotic is a chemical compound that is toxic to other bacteria and is produced by a living thing, usually a bacterium. In a complex environment like soil, organisms undoubtedly use antibiotics to regulate the growth of competing microbes. Soil microorganisms frequently produce antibiotics.

Bacteria and fungi are microorganisms that produce antibiotics that help prevent or treat disease. With the invention of penicillin in 1941, antibiotics gained widespread recognition. Since then, they have fundamentally changed how bacterial infections in humans and other animals are treated.

mihalych1998 [28]

Answer:

Amoxicillin inhibits an enzyme required to build cell walls in bacteria.

Since humans have cell membranes, they are unaffected by amoxicillin.

Explanation:

Antibiotics are specifically designed to target bacterial cells, therefore, they don't kill human cells.

Amoxicillin, a type of penicillin, inhibits the biosynthesis of bacterial cell wall. The bacterial cell wall contains peptidoglycan that constitutes almost 95% of the cell wall in some Gram positive bacteria and as little as 5-10% of the cell wall in Gram negative bacteria. Amoxicillin inhibits the cross linkage between the linear peptidoglycan polymer chains that make up a major component of the cell walls of both Gram positive and Gram negative bacteria.
