Cellular respiration is an important cellular process during which cells use sugar to create ATP, a form of energy that can be used by your cells. Cellular respiration occurs across the membranes of the mitochondria. During one step of cellular respiration, hydrogen ions flow from high concentration to low Concentration across the inner mitochondrial membrane. Ihis movement of ions causes a small electrochemical voltage This provides energy to create ATP. What type of cellular transport occur during cellular respiration?

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.
