Jamal wants to know how fast his skateboard can roll down the ramp in front of his school. so, jamal places the back of the
skateboard even with the top of the ramp and times how long it takes before the front of the skateboard reaches the end of the
ramp. after he records the time, he performs this procedure again four more times and calculates the average time.
during his experiment, jamal demonstrates
oa. renovation
ob. replication
oc. repetition

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.
