AQA A2 Biology BIOL5 - 17th June 2015

Doesn't ATPase create ATP? not break it down?
I didn't do as much revision as I'd liked... I flopped that table
I may have misread to question... maybe it said what created ATP... well I messed up the very first table XD

it's probably wrong because i didn't revise it but i wrote tropomyosin for the last one, and actin filament and myosin heads for other two can't remember the order

DID NOT ONE OTHER PERSON FIND THIS PAPER HARD WAAAAAAA

Lol dunno . The other would be adpase right??

Guys as well as writing about homeostatic temperature and chemo receptors and taxes/tropisms I also swore about change in water potential (water is external environment that changes) and anaerobic respiration as response to changes in O2 in the environment. Is that wrong?

Is there such thing as adpase?

Is there such thing as adpase?

It's ATPase, breaks down ATP into ADP and Pi, providing energy for myosin head to move and detach etc.

Hey guys for the monoclinal antibody one i said all the competitive inhibition stuff correctly but also randomly mentioned antibodies destroying growth factors. Would that negate my marks??

Does anyone know the answer to the DNA methylation question?

2.27:1 will just depend on graph reading but hopefully we're right

Antibodies bind to the growth hormone, so that the growth hormone can't bind to the cancer cell.

Oh ****. I wrote "b" at the top of my plan, but I wrote (and planned) the essay on responding to internal/external conditions.

I used extra paper too and I think I wrote 10b on that too.

****!

atp synthase makes atp atpase breaks down atp?
