Is this a good scientific question?
"is the lifespan of snowshoe hares, which are white in the winter and brown in the summer, affected by levels of
winter snowfall? "
yes, because the question is specific.
no, because the question cannot be tested in a laboratory.
yes, because the question has already been answered.
no, because the question does not lead to a hypothesis.

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.
