For the monoclonal antibodies one I thought it was about how they can bind to a toxic or radioactive substance and can then be inserted without damaging other body cells so just cause harm to the tumour? Idk

I think it was to do with osmosis and how as people with diabetes are unable to control their blood sugar levels they had higher concentration of sugar (so lower concentration of water in the blood than in the cells). Therefore, the water moves from a high to a low concentration through the cell’s partially permeable membrane.

I think this exam was good. There were no 6 mark required practicals, and most of it was just knowledge, barely any applying

monoclonal antibodies are produced from one b-lymphocyte that produces antibodies specific to the cancer cell
this make the monoclonal antibodies also specific to the cancer cell
these then bind to the cancer cell and alert other white blood cells to destroy the cell
(Original post by Erevising45)
What did everyone put for the monoclonal antibody question? I think I put something about how antibodies bind to molecules in the blood so they can be detected and destroyed.
