Anyone else freaking out over OCR Biology F212?

Hey guys, I know I'm not alone, but is anybody else feeling hugely unprepared for the upcoming ocr biology unit 2 exam? For some reason I just feel like I can never know enough! If anybody can suggest some good revision techniques, websites and possible predictions, it would be much appreciated! :biggrin:

FOCUS AREAS FOR F212 JUNE 2015

2.1.1. Biological molecules

c) – breaking and making peptide bonds – diagram/drawing
f) – bonds/tertiary structure (THIS MAY WELL BE LINKED WITH AN ENZYME STRUCTURE QUESTION)
g) Hb as quaternary structure?
j) alpha / beta glucose structure (diagram?) and formation of polysaccharides (Glycogen!!!) including functions of these
l) formation and breakage of glycosidic bonds
n) GLYCOGEN!
r) biochem tests
s) colorimetry – glucose conc HSW – LIKELY!!

2.1.2 – Nucleic acids
Structure of DNA/RNA types
f) roles of DNA/RNA – concept of ROLE in protein synthesis?

2.1.3 Enzymes
a) – definition and features of enzymes - LIKELY
b) – intracellular enzymes
c) theories lock and key/induced fit/ lowering activation energy – graph? –LIKELY
d) enzyme conc and temp explain effects on enzymes
e) enzyme experiments HSW – Temp and concentration most likely – practicals to test these
f) reversible/non reversible – non-competitive most likely
g) prosthetic groups/coenzymes/cofactors
i) medicinal drugs inhibiting enzymes – very LIKELY – antibiotics etc HSW

2.2.1 diet and food production
c) diet /CHD linked to DIET - LIKELY
h) agrochemicals

2.2.2 Health and disease – VERY LIKELY TOPIC!!!
a) define disease
b) parasites and pathogens – difference between
c) Malaria and HIV are most likely TB came up in 2013 - analyzing global impact of diseases – graphs and also how the diseases spread/prevention etc
e) define antibody/antigen
f) primary defences
h) structure of antibodies – diagram didn’t come up yet
k) primary/ secondary response to antigen exposure
l) compare passive /natural etc
m) – Ring and herd Vaccination?
n) HSW – Flu vaccine / mutation – government responses
o) –sources of medicines HSW – linked to agriculture/biodiversity
p) – smoking –linked to the diseases – emphysema/bronchitis/cancer – not come up for ages

2.3.1 Biodiversity
a) definition of habitat/species
b) biodiversity at all levels, species, genetic etc – not come up yet
c) importance of measuring biodiv
f)Simpson’s Diversity index

2.3.2 classification – LIKELY AREA TO BE TESTED!!!
a) define terms
d) features of the different kingdoms
e) binomial
f) modern classification techniques – cytochrome c, amino acid sequence etc
h) 3 domain vs 5 kingdom

2.3.3 Evolution
c) different types of variation – examples
e) behavioural, physiological adaptations – Xerophytes possibly or ad
h) DNA/molecular evidence for evolution
i) VARIATION adaptation and selection contribute to evolution – VERY LIKELY
j) evolution of resistance – long q – impact on humans? – linked to Flu/vaccines/food – VERY LIKELY

2.3.4 Maintaining Biodiversity
a) reasons for conservation – long q?
b) global climate change on biodiversity – LIKELY!
c) benefits to agriculture
d) in situ ad/disadvantages
f) CITES/Rio convention
