Anew bacterial life form is discovered on mars. the meselson and stahl experimental protocol is used to determine the mode of dna replication in this species. the bacteria is grown first in heavy nitrogen (15n) and then switched to 14n, and then centrifuged. it is discovered that dna replicates via the conservative mode of replication in this species. what experimental results led to this conclusion?

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.
