Nitrogen essay featured:
* DNA and RNA in eukaryotae and prokaryotae
* Amino acids, ability to peptide bond due to amine/carboxylic acid groups
* an astoundingly bad diagram of amino acid structure done in leaky fountain pen
* proteins as enzymes, pigments, channels for facilitated diffusion, (some) hormones + examples
* 'heavy' nitrogen isotopes used as markers in biological research
* nitrogen cycle
* excretion of nitrogenous waste + use of leftovers as respiratory substrates
* nitrogen in the blood -> decompression sickness
* excess fertiliser -> eutrophication
* conclusion: NITROGEN IS WELL GOOD UNLESS YOU HAVE TOO MUCH AND THEN IT IS 2 MUCH 2 HANDLE
