so what were we supposed to write in the second point?yeah, i did the past papers before giving the paper, they accept either reversible competitive inhibition, reversible non-competitive inhibition or non-reversible non-competitive inhibition

are we suppose to write the term?. cant we just explain how it fits and inhibits??
how many marks did it have?? 3 i guess, anyway you had to write the name and then 2 or 3 points about the features of the inhibition you named, such as where does the inhibitor fit, what change it brings about and how it effects the enzyme catalysed reaction.
In the last question of the paper, about phosphate ions i wrote the following 3 uses: synthesis of ATP, formation of phospholipids and synthesis of DNA/RNA. Then i vaguely linked them to growth
Basically they had asked about the uses of phosphate ions right??

ATP is no way linked to growth the question asked what is the role of phospates in growth so synthesis of DNA/RNA with little explanation was enough
ATP is for energy and energy is needed for growth, similarly phospholipids are needed for the cell surface membrane of newly formed cells (for growth), DNA is needed for cell replication (nuclear division) and RNA is needed for protein synthesis, and proteins are also required for growth.
I wrote these explanations, I guess ATP is correct if linked with energy...no?
actually i dont knoware we suppose to write the term?. cant we just explain how it fits and inhibits??
i wrote -synthesis of ATPIn the last question of the paper, about phosphate ions i wrote the following 3 uses: synthesis of ATP, formation of phospholipids and synthesis of DNA/RNA. Then i vaguely linked them to growth
Basically they had asked about the uses of phosphate ions right??
-formation of neuleotides
-for formation of chromatids to increase the growth cell division and so the growth increase
ATP is needed i think
this is exactly how it looked ^^View attachment 11769
I guess this was the photomicrograph of the plasma cell which was given. Either this or something very similar!

ohh god! the figure was too confusing. what did u guys labbelled??
It was rough, although a lot of ppl wrote smooth as well.
nucleus, mitochondrion and rough endoplasmic reticulum.ohh god! the figure was too confusing. what did u guys labbelled??

it is simply the SAME EXACTLY
I thought so too, i found this from google images, although there were many photomicrographs of plasma cells, I immediately recognized this one as the one given in our paper.
Yes, it was difficult to distinguish it as either RER or SER, but it was RER since they had asked about the structure's importance to specific role of plasma cells. RER is required for synthesis of proteins and hence antibodies, since antibodies are (glyco)proteins. SER has no importance to the specific role of plasma cells.How was it rough? :/ It looked smooth

alrite. And i wrote DNA and not nucleus , do u think they'll give marks on that??

And what about the second ques?? transport mechanism- with protein and without???
