Its not about not owning them; they dont make papers for Jan units. BIOL5 is only made for June exams. Its only for Chemistry that you get Unit5 papers in Jan. So theres only 2 papers for Biol5 you can practice with: the specimen one and June 10

is anyone else finding the homeostasis section quite hard?
i thought i would have found this section quite easy tbh, but going over past exam questions and stuff makes me realise how hard blood glucose control and temperature regualtion is.... :frown:

is anyone else finding it difficult?
i cant seem to get my head around glycogenolysis, glucogenesis and gluconeogensis?!?! if those are even correct!! lol
eurghh this exam is going to be hell :frown:

Are you using the nelson thornes book? Its pretty good for this topic :smile:

I did my notes for homeostasis on a powerpoint presentation, I can upload it if you want. It might not be of much help...

Remember:
Lysis is splitting
Genesis is formation (birth)
Neo is new
Glyco and gluco = glucose
Gluconeogenesis is the making( formation) of new (neo) glucose (gluco).
Glycogenoslysis is the splitting (lysis) of glyocgen.

Hope this hasn't made you more confused. But yeah, remembering the meaning of the terms seems to work for me.

I have revised all the topics, although I cannot remember the lines and zones in the sarcomere. I know nothing about the menstrual cycle because I missed the 1 lesson we spent on it, and we have not been taught anything about cystic fibrosis :/

Going well so far! :redface:

The sacromere, here's how I remember it:

I-Band is the space inbetween the two myosin filaments.

Therefore the A-Band is the other, which is the myosin plus where it crosses over the actin.

And Cystic Fibrosis isn't too difficult. Its caused by a mutant recessive allele that codes for a ion channel protein. This causes the ion channel for chloride ions to not function correctly on the membranes of epithelial cells. Without the chloride ions diffusing out of the cells, water cannot follow, meaning the mucus outside the cell becomes thick and sticky.

It causes sperm ducts and pancreatic ducts to become blocked, and obviously breathing difficulties and increased risk of disease.

Hope this helps :smile:

How does homeostasis and negative feedback control the level of glucose in the blood?

hey im stuck on plants atm, basically i know nitrate are used to make proteins in plants with glucose. Yet if there is a lack of nitrates that means there is a lack of protein being made, so what happens to the glucose that cant be converted to protein?

Thanks a lot, and by assuming the sperm ducts have an increased risk of being blocked then there's an increased risk of infertility? :biggrin:

I'm not looking forward to this exam in general. I need an A overall, and so need around a B in this paper. But it seems a mammoth task right now!

i've barely done anything so far, feel really bad bout it :frown:

, i'm kinda freaking out about the essay aswell, does anyone have a big list of mark schemes for all the different titles there has been, if so it would be really helpful to me, thank you :smile:

i don't think we got taught anything about cystic fibrosis either:/

I think Cystic Fibrosis was an example for a use of Gene Therapy rather than just learning about the actual condition.

You'll only need 60% in this exam to get an A, that works as some encouragement, but try not to think "Oh, well, I can get 60% and get an A, I don't need to revise as much as I thought!"

I have written 1 essay, and I got it marked at a C grade by my teacher. I haven't written an essay since -.- my teacher gave me no useful feedback and I don't know how to make it better, so why write another essay if it's just going to be the same as my last?

Does anyone object to me writing up my essay on here so I could receive some constructive criticism?

Going to start posting my exam-time condenced notes for people if they want them, probably will start later today or tomorrow :smile:

.

I've covered about half of the syllabus and memorised it, how is everyone else doing? I hope to have everything more or less memorised by Wednesday so I can start doing past paper questions and essay practice for the last two weeks.
