very few exceptions, all of the physiological

actions in your body depend on ATP. You can

neither function nor survive without it.

ATP is made in each and every cell of your

body by structures called mitochonodria. The

mitochodria, however, cannot make ATP out of

nothing. To make ATP, your cells need two

major resources: Glucose (blood sugar) and

Oxygen. The glucose comes from your food.

Your body breaks down the food and from this

derives the glucose. The oxygen you breathe in

through the process of respiration.

While this may sound simple, there are

many ways and many places this process can

break down. Lets look at a few.
