Question

Ampicillin, amoxicillin, mezlocillin, and penicillin G all :

A- All of the choices are correct.
B- are semisynthetic.
C- have resistance to the action of penicillinase.
D- have an expanded spectrum of activity.
E- target the cell wall.

Answer 1

Ampicillin, amoxicillin, mezlocillin, and penicillin G are all semisynthetic penicillin drugs that target the cell wall of bacteria and inhibit the crosslinking of peptide chains. This leads to bacterial cell death.

Step-by-step explanation:

Ampicillin, amoxicillin, mezlocillin, and penicillin G are all semisynthetic penicillin drugs. These drugs have been chemically modified to improve their potency, spectrum of activity, and other characteristics. They all target the cell wall of bacteria and inhibit the crosslinking of peptide chains during the biosynthesis of new peptidoglycan, causing bacterial cell death.
