Final answer:

β-lactamase functions as an enzymatic inactivation resistance mechanism.

Step-by-step explanation:

The function of β-lactamase as a resistance mechanism is enzymatic inactivation. β-lactamases are bacterially produced enzymes that cleave the β-lactam ring of susceptible β-lactam antimicrobials, rendering them inactive and conferring resistance.

The function of β-lactamase in bacterial resistance to antibiotics is classified as enzymatic inactivation, where the enzyme breaks the β-lactam ring, making the drug inactive.

The function of β-lactamase is described as enzymatic inactivation. β-lactamases are bacterially produced enzymes which render β-lactam antimicrobials inactive. They achieve this by cleaving the β-lactam ring within these antimicrobial molecules. Once the β-lactam bond is broken, the drug loses its ability to inhibit cell wall synthesis, rendering it ineffective against bacteria.
