Test yourself: Biology
Section I, Part B, for 7 marks
Fungi are a natural source of antibiotics. A scientist developed a new antibiotic by exposing a fungus to radiation.
Information relevant to this antibiotic:
- It stops the activity of an enzyme in pathogenic bacteria.
- It has no effect on a similar enzyme in humans.
- The chemical composition of the enzyme in human differs from the enzyme in the pathogenic bacteria by two amino acids.
- It is used to treat humans infected with the pathogenic bacteria.
Using this example and other relevant knowledge, describe how advances in our understanding of biology have implications for society.
