This is a good list. I think there may be some stuff on homeostasis and possibly more on the kidney. Anyone got predictions for the essay?
Mabye something on atp or inorganic ions?
thanks guys im not sure i have a feeling water will come up as an essay -hope u guys do well xx
My bio teacher sent us a message of topics still to be covered, they're pretty much in line w yours! Have a look:
Topics that have not been covered yet (e.g. for paper 3);
biological molecules (sugars, starch glycogen etc)
eukaryotic cell structure
absorption (enzymes, active transport, cotransport etc),
Big topics still not covered; Blood
response to stimuli (cardiac cycle, plant hormones, responses)
blood sugar control
On the specimen paper one of the questions is the importance of movement in living organisms. I feel like that fits in because it relates to many topics that have not come up yet. Does anyone think they'll put a question on the specimen paper on the exam though?
If the essay was ‘the importance of ATP’ what would you talk about? I know it sounds so obvious but when you think about it, it’s hard to think of 5 big topics regarding ATP you can talk about (or maybe it’s just me)
How long would you guys recommend to spend on the essay at the end?
2 sentence intro..
1. The fundamental process of mitosis and meiosis (both require ATP)
2. segway into the formation of proteins, then the importance of ATP in carrier proteins to move substances across membranes)
3. Importance of ATP in respiration (ATP required in the phosphorylation of glucose in glycolysis)
4. importance of ATP in synapses (reforming acetyl choline requires ATP)
5. segway to muscle contractions (ATP needed to bend myosin head, and to break myosin-actin attachment then bring it back to original place)
