hi :)! Could you tell me what was in question 6 besides translation and antibody production? Because I have no memory of these questions appearing on paper 2 and now I think that probably I should've chosen that one.
to-silverglass said: wait there was antibody production in question six? where?
as close as i can remember, question 6 was as follows
6. a) List four functions of membrane proteins [4]
b) Explain the process of translation in the synthesis of polypeptides [8]
c) Explain the process of antibody production in the immune response [6]
hmm Q5 was
a) Draw the structure of DNA [5]
b) (can’t remember b, but it was also worth 5 points)
c) Discuss the effects of gene modification using a named example [8]
and i don’t remember much about Q7 except that a) was discuss the optimum pH, temperature etc. and other properties of a named amylase or something similar

i read the question like 97 times, i’m pretty sure it’s translation (man i hope i’m right it didn’t even occur to me to question myself afterwards shit)
hmm i wrote basically
macrophages engulf antigens → antigen markers → recognised by helper t-cells stored in lymph nodes → t-cells activate appropriate B-cells → B-cells divide/differentiate and produce antibodies → antibodies target antigens → after antigens are destroyed, some B-cells stay behind as memory cells → this is why we have immunity to some diseases eg chicken pox after having suffered them once
but i didn’t remember what happens to the rest of the B-cells so i didn’t mention them at all… idk i guess they either disappear or deactivate
also i’m pretty sure i wrote β-cell instead of B-cell oops but i guess maybe it doesn’t matter that much??
