Answer :
Final answer:
Resistance in bacterial strains develops when the strain is able to inactivate the drug. For example, strains resistant to penicillin produce beta-lacmase which breaks the beta-lactam ring (Option B).
Explanation:
The enzyme produced by penicillin-resistant bacterial strains is beta-lactamase, which inactivates the drug by breaking down its beta-lactam ring structure.
Resistance in bacterial strains such as penicillin resistance, develops when the strain produces an enzyme that inactivates the drug. In the case of penicillin, the resistant strains produce an enzyme called beta-lactamase. This enzyme is capable of breaking down the beta-lactam ring structure of penicillin, thus rendering the drug ineffective against the bacterial strain.
Thus, the correct option is B.

Resistance in bacterial strains develops when the strain is able to inactivate the drug. For example, strains resistant to penicillin produce b. beta-lactamase which breaks the beta-lactam ring. Thus, option b) is the answer.
Resistance in bacterial strains emerges when the strain acquires mechanisms to neutralize the effects of antibiotics. For instance, in the case of penicillin resistance, bacterial strains produce an enzyme known as beta-lactamase. This enzyme is capable of breaking the beta-lactam ring, which is a crucial structural element present in many antibiotics including penicillin. The beta-lactam ring is responsible for the antibiotic's ability to inhibit bacterial cell wall synthesis.
When bacterial strains produce beta-lactamase, it cleaves the beta-lactam ring of antibiotics like penicillin, rendering them ineffective in inhibiting cell wall formation. This adaptation allows bacteria to survive in the presence of antibiotics that would otherwise target and destroy them.
Understanding these resistance mechanisms is vital in combatting antibiotic resistance. Developing new antibiotics or combination therapies that can bypass or inhibit the action of beta-lactamase is essential to ensure the continued effectiveness of antibiotics in treating bacterial infections and preventing the spread of drug-resistant strains.
The correct option is: b. beta-lactamase.
