In humans, the antibiotic amoxicillin (a type of penicillin) is used to treat certain bacterial infections. Complete the sentenc
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.
