Yep...im really enjoying it....the textbook is fantastic for this unit...ive found that using animations from youtube on resting/action potentials and light dependent/independent has really helped a lot. Yeh there is so much content to learn....and its only worth 30% of the A2!!! There is just as much work here as Unit 2 of AS and at least twice as much as the first unit in AS!! This should be worth a bit more than 30%! Structure of liver is killing me!
My teacher just keeps skipping parts of the syllabus- its really annoying like below:
(r) evaluate the experimental evidence for the theory of chemiosmosis (HSW1);
I like to use the CGP revision guide- but the experiments listed on page 42 seem to be 'describe' rather than 'evaluate'. So what did you learn for this part? Any help appreciated.
Okay thanks...Also do we need to know about the RQ or the relative energy values? Teacher taught us RQ and its in the revision guide but in the heinemann book and syllabus its relative energy values.
Wheres everyone from last year? I seem to remember the OCR biology threads being quite active

Do you mind sharing the links - I'm thinking of adding 'useful resources' to the 1st post...

Me too. Well. Learn it all the be on the safe side I would.
(c) Explain how respiration in plants and animals depends upon the products of photosynthesis; Photosynthesis is the main means by which plants, algae and many bacteria produce organic compounds and oxygen from carbon dioxide and water (green arrow). The organic compounds are used again in photosynthesis (red arrow). Whereas, the oxygen produced by photosynthesis is used for respiration. Oxygen was first released as a product of photosynthesis, once the atmosphere contained free oxygen organisms evolved that could use the oxygen for aerobic respiration and release CO2 back into the atmosphere. http://upload.wikimedia.org/wikipedia/commons/thumb/2/2f/Auto-and_heterotrophs.svg/300px-Auto-and_heterotrophs.svg.png
