DNA polymerase is a primer-dependent enzyme that functions only in the 5'-3' direction. These are the two most fundamental concepts to understanding this enzyme. Based on this, which of the following enzyme pairs are analogous in prokaryotes and eukaryotes?
a. DNA pol I : DNA pol α
b. DNA pol II : DNA pol β
c. DNA pol III : DNA pol δ
d. All of the answers are correct

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.
