Susan then goes outside to measure the light intensity that different parts of her yard receive. She notes that part of her lawn receives sunlight at an intensity of 250 and other parts receive sunlight at an intensity of 450. She decides that she will try two different things to get the grass to grow. First, she will try watering the grass more often. If that doesn’t work, she will increase the light getting to the grass by cutting down a few trees. Predict the results of each treatment and explain your answer.

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.

Where's the picture of the model?
