Some bacteria produce the enzyme penicillinase, which breaks the beta-lactam ring in the penicillin molecule and converts it into penicilloic acid, which is harmless to bacteria.  This is an example of which of the following mechanisms of antibiotic resistance? which option below is the answer? Destruction or inactivation of the antibiotic by the microbe  Preventing penetration to the target site within the microbe Alteration of the drug’s target site(s) within the microbe None of the other four answers are correct Rapid ejection (pumping) of the drug out of the microbial cell
