Match the words in the left column to the appropriate blanks in the sentences on the right.
Amoxicillin inhibits an enzyme required to build ______ in bacteria.
Since humans have _____, they are _______ by amoxicillin.
Words: unaffected, lysosomes, vacuoles, cell walls, cell membranes, also affected, DNA, RNA.

Answer 1

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

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

Step-by-step 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.
