I cant see a thread for the New OCR A2 F212: Communication, Homeostasis and Energy

so thought I'd make one...

Any queries or advice in this thread please.

It's been a while since you posted and nobody's replied yet...maybe you should check out MarkedbyTeachers.com, TSR's sister site. It has the largest library of essays in the UK.

They've got over 160,000+ essays, projects, assignments, coursework etc.. all written by GCSE, A Level and Uni students. You get access either by publishing some of your own work, or paying £4.99 for a month's access. Both ways give you unlimited access to all of the essays.

All their documents are submitted to Turnitin anti-plagiarism software, so it can't be misused, and the site’s used by hundreds of thousands of UK teachers and students.

Hopefully you'll find it useful

I'm doing this module in January

The module is deceivingly short, yet there is such a large amount content involved!!

ADP,AMP,NADP,NAD,ADH

All those cycles aswell!!

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!

[letia]

there will be a lot of revision this xmas! xx

Lets bump this thread up. People were so helpful for the as exams last year .

[BHAM!]

I hate having no past papers and just the old ones =(

[Priyanka1992]

january exam...!

Interesting stuff but no way just worth 30%.

Need to start revising/learning this now.

And past paper questions anyone...?

[skatealexia]

Agreed, there seems too much information.

[lil_miss_rapunzel]

Yep, I also think there is loads of content for an exam that's only 15% of our total A-level...

Haven't really started revising yet but I feel okay about the exam...a hell of a lot more confident than I am for Chemistry anyway!

[skatealexia]

I feel more confident about biology than chemistry too.

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.

We learnt the stuff from the heinemann text book.

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...

Yeah I will...just trying to find content to cut out - I have 5 exams and definitely not enough memory to fit everything

P.S. any useful links/resources/notes post here and I'll add it to the 1st post.

(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.

Is that all we need to know for this part?

this unit is much better than the unit 2 AS unit on biodiversity etc
