Immunity is one of the 11 main topics in our A Level Biology (Cambridge (CAIE) 9700) question bank, and about 5% of its real questions come from it. Tayyari Karo has 30 real questions on this topic from 2021 to 2026, from Paper 1, Paper 2; 26 are multiple choice and marked instantly, and the rest are structured questions with a model answer. By difficulty: 22 medium, 4 hard, 4 easy.

Which type of cell is fused with a myeloma cell in monoclonal antibody production?
Answer: A. B-lymphocyte
Antibody-producing B-lymphocytes are fused with myeloma cells to form hybridomas.
The hybridoma method is used for the production of monoclonal antibodies. Which two types of cell are used in this method?
Answer: C. tumour cell and B-lymphocyte
A hybridoma is formed by fusing an antibody-producing B-lymphocyte (plasma cell) with a tumour (myeloma) cell to give a cell that divides indefinitely and secretes a single antibody.
What will be produced by the division of memory cells during a secondary immune response?
Answer: B. plasma cells
Memory B cells divide rapidly during a secondary immune response to form plasma cells, which secrete large quantities of antibody.
Repeated infections with malaria result in more effective immunity to malaria. Which type of immunity is responsible for the more effective immunity?
Answer: C. natural active
Repeated natural infection stimulates the person's own immune system to produce memory cells and antibodies, giving natural active immunity.
Which types of cell are stimulated to divide by the cytokines produced by T-helper cells?
Answer: D. B-lymphocytes and T-killer cells
Cytokines released by T-helper cells stimulate clonal expansion (division) of both B-lymphocytes and T-killer cells as part of the specific immune response.
What are functions of T-lymphocytes?
1 production of cytokines
2 production of toxins
3 recognition of an antigen bound to an antigen-presenting cell
Answer: C. 1 and 3 only
T-lymphocytes produce cytokines and recognise antigen presented on antigen-presenting cells; production of toxins is not a function of T-lymphocytes, so only 1 and 3 are correct.
