Also i've been recomended by a friend who used to be a teacher to really know:

#Respiration
#Photosynthesis
#Carbon and Nitrogen Cycles
#Enzymes

Of course knowing everything is always nice, but those are hot topics apparently!

Enzymes....hmm. They always come up! Not much to talk about them though....well, not that much. Digestion, their structure, in photosynthesis and respiration etc. (CoA). Can anyone think of any other topics that include enzymes?

you could do the factors that affect enzymes - i think that was mod 1
and their aplication to gene technology etc - reverse transcriptase, insulin etc
dont enzymes break down neurotransmitters aswell?

Also:

In diagnosis -Biosensors (glucose oxidase and peroxidase), diagnosis of pancreatitis
Induced fit theory
Things that effect them (temp, pH, inhibitors)
Their structure - all globular proteins

+The things Biscuit said. More than enough there I'd say, covers a few modules too. I think enzymes could be a pretty good question.

For 'Cycles In Biology' I've got:

Photosynthesis-light independent
Respiration-Krebs Cycle
Nitrogen Cycle
Carbon Cycle
Reproduction

Then I wasn't sure what exactly counts as a cycle for example could you include these even though they aren't cycles as such?
-Negative feedback loops (homeostasis etc)
-Circulatory system?

You could get neruones into that title, ie. Na+ channels open etc. and then it loops back round to active transport to regain the resting potential. Meiosis, mitosis can get into there too. The heart could be breifly mentioned too? Ie. aorta and ventricles pumping blood around the body with oxygen etc.?

Immunology
o Lysosomes in white blood cells - phagocytosis
o Blood clotting - prothrombin-thrombin; TPA

Digestion
o All the Proteases - exopeptidase/endopeptidase
o Lipase
o Amylase

Muscle Contraction
o ATPase

Receptors
o Acetylcholinesterase - breaks up the neurotransmitters

Gene Technology
o Restriction endonuclease
o ligase
o reverse transcriptase - ( use of that in HIV possibly?)

Ok this is probably a stupid question but what's the difference between and inorganic ion and a mineral ion?

Coz we've been given a few essay titles, one being 'The functions of mineral ions in plants and animals' and another being 'Inorganic ions include those of sodium, phosphorus and hydrogen. Describe how these and other inorganic ions are used in living organism' and I wasn't sure what a mineral ion is exactly- I would have written about: H+ Na+ Ca2+ K+ etc.

Just a random brainwave when i was looking through all my notes. How about a question on the blood? I haven't seen one over the last 5/6 years. I mean you've got got transport of gases (all the stuff with carbonic acid and hydrogencarbonate ions from module 6), immune system, hormones, transport of food, buffer, distributor of heat, blood groups.

What do people think?

Ah yeah good point.

Yeah your right about the topic, i just mentioned blood because that hasn't been done recently. But there are too many things they could ask =/

Protein structure has come up..

Carbohydrate structure

Would be it be too obvious to expect lipids?!

I didn't think they did synoptic papers in January? Isn't there only June past papers on the website?
