The answer is nitrogen. Free-living or symbiotic bacteria known as diazotrophs 'fix' atmospheric nitrogen into nitrates and nitrites. The bacteria use an enzyme that combines gaseous nitrogen with hydrogen to produce ammonia. Ammonia is in turn converted to nitrites and nitrates through nitrification. While plants do not have access to atmospheric nitrogen, then can assimilate ammonium, nitrites and nitrates. Symbiotic bacteria can live in the root nodules of legumes and provide the host plant with ammonia in exchange for carbohydrates.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."

Atp is is our little "pocket" of energy. of course, if you have too little, then it means you have too little energy, and you'll pass out. the way to not have enough, is to have no energy sources (glucose, fats, proteins). you can't have too many atp molecules. cycles like the krebs cycle produce it, but if you have too much of any substrate (or too little for that matter), the cycle stops and atp is no longer made (it stops until substrate levels are such that the process can go on). in any case, this is unlikely since atp is constantly hydrolyzed and remade, even while you're asleep. you won't have too much. if you have zero, you are dead or dying.
