AQA AS LEVEL BIOLOGY COMPREHENSIVE
EXAM 2026 QUESTIONS WITH SOLUTIONS
GRADED A+
◉ Explain how monoclonal antibodies target cancer. Answer: 1) Cancer
cells have antigens called tumour markers that are not found on body
cells.
2) Monoclonal antibodies can be made that will bind to the tumour
markers.
3) You can also attach anti-cancer drugs to the antibodies
4) Antibodies come into contact with the cancer cells and bind to the
tumour markers
, 5) This means the drug will acuumulate in the body where there are
cancer cells.
6) side effects of an antibody based drug are lower than other drugs
because they accumulate near specific cells
◉ Describe three functions of proteins. Answer: three from:
Enzymes = break down large food molecules or help to synthesise large
molecules
Antibodies = involved in the immune response, they have variable
regions.
Transport proteins = transport ions and molecules across membranes
