Explain the forces in the diagram below (up, down, left and right). try to use science vocabulary in your explanation. (balanced and unbalanced)

The 2 forces in the up and down directions are completely balanced and will result in a net force in the up and down direction of 0.  The forces left and right are unbalanced.  That means the greater force will have a net pull in that direction of the difference between the two directions.  632 - 487 = 145 N in the right direction is the net force.

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.
