Suppose you are visiting the equator. It is noon. The Sun is at its highest point in the sky for the day, which is directly over your head. You call a friend on the phone, and
she says it is also noon where she is but the Sun is not directly overhead at that
location and time. It is a little lower in the sky for her. Compare the longitude and
latitude where you are with the longitude and latitude where your friend is. Are they
alike or different? How do you know?

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.
