Worked Solution & Example Answer:A disease-causing bacterium has the following structure - VCE - SSCE Biology - Question 7 - 2006 - Paper 1
Step 1
The kind of antibodies most effective against this type of bacterium would be
Answer
To effectively target a disease-causing bacterium, the antibodies must be able to bind specifically to its surface structures. In this case, the bacterium's structure appears to have spikes that could interact with antibodies. The best choice among the options would be those antibodies that can effectively bind to these spikes.
- Subpart B provides an antibody shape that is best suited for binding to the unique structural features of the bacterium, enabling it to neutralize or mark it for destruction by immune cells. If examining closely the shape of the antibodies is crucial, B offers the most appropriate configuration.
