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!

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

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!
