(b) (i) inhibiting the ability to turn glucose into energy
(ii) inhibiting the ability to construct its cell wall
(c) antibiotics are effective only against bacteria, fungi and parasites and not viruses

Q3:
Ans: The passage states that when antibiotics are overused, the bacteria are likely to become resistant and the antibiotic becomes less effective against a particular type of bacterium. Furthermore, it mentions that if the antibiotic treatment is stopped abruptly, some bacteria may have had some exposure to antibiotics and have consequently built up a resistance to it.

Q4:
Ans: As a doctor, I would advise the patient that it is crucial to complete the entire course of antibiotics prescribed, even if they start to feel better before finishing the medication. This is because if the antibiotics are not taken for the full prescribed duration, some bacteria may survive in the body and become resistant to the antibiotic. This can make the infection harder to treat in the future and also contributes to the wider problem of antibiotic resistance, which can affect the effectiveness of these drugs for others.
