The location of two hikers is marked on the topographic map at right as points Q and S. Each hiker climbed to point R along the path indicated by the arrow. What was the change in elevation for
the hiker who took the steepest path to point R? Record your answer in the box below. Be sure to
use the correct place value.

The person who took the steepest path is obviously S, the contour lines are closer together indicating that. The change in elevation between the point were the hiker starts and ends is 50 meters.

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.
