6Why is there salt in the sea?
7Give me an example of a protein
8What effect does an enzyme have on a reaction?
9How can antibodies complementary to all the various pathogens come about?
10The differences between U.V. and X-ray spectroscopy
11Why in a sample of molecules the energy given out in form of the electromagnetic spectra was less than that absorbed (whereas it was the same in a sample of atoms) 
12How the spectra would be affected if an atom was bonded, as opposed to alone.
13What my understanding of proteins was, what the bond between the amino acids was called. Then to draw it and I was asked about it’s properties.
14To figure out the 3D shape of the peptide bond

23What are steroids?
24Why does insulin work better when injected rather than taken orally?
25Talk about electrophoresis, then genetic recombination
26Draw ethanol and propane, what are they’re states, why do they differ?
27How would you adjust ethanol to make it a stonger acid?

45(gives a diagram) Which of these molecules will be able to diffuse across the phospholipid bilayer?
46How does this process[dehydrogenation] happen?
47How can we tell that it’s this part of the molecule that is cleaved off rather than this part?
48What are some genes dominant and some recessive?
49When I snap this glow stick, why does it produce a funny colour?
50If a general reaction is written A + B = C + D, can you work out the equation for the equilibrium constant.
51(following on from the above question) If Kc = 3, C = D = 2, draw me the curve for the rate of reaction when changing one of the variables.
52A question about the force of intermolecular attractions between amino acids and proteins
53On the paper there was basically “AGTCATATCCGA”…etc – they asked me to say what it was, and why i knew it was DNA and not RNA.
54They asked about a molecule, asked to describe it, how would I dissolve it (like with like)
55Asked to define acids and bases – then say whether the given molecules could act as acids or bases.
56Asked about why I liked oxidative phosphorylation, and to outline a model of it.
57Asked how the protons specifically helped synthesise ATP.
58About why ethanol made people drunk?
59About the role of phosphate in blood
60About oxidative phosphorylation and photophosphorylation – asking me to compare the two (similarities, differences)
61They asked me to draw two optical isomers and discuss they’re uses
