Amuscle cell has a long, thin structure. which statement best explains why these two types of cells have different structures?

Only one type of cell was given, but different types of cells are structured differently in response to what function they need to perform.

For example, muscle cells are like that because they need to be flexible. Bone cells, however, are compact. This is because bone cells need to be durable, to keep the body together.

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.
