Energy Systems
Adenosine triphosphate (ATP) is the usable form of chemical energy for muscular activity. It is stored in most cells, particularly in muscle cells. Other forms of chemical energy, such as that available from the foods we eat, must be transferred into ATP form before they can be utilized by the muscle cells.

Famous quotes containing the words energy and/or systems:
“Perhaps catastrophe is the natural human environment, and even though we spend a good deal of energy trying to get away from it, we are programmed for survival amid catastrophe.”
—Germaine Greer (b. 1939)
“People stress the violence. Thats the smallest part of it. Football is brutal only from a distance. In the middle of it theres a calm, a tranquility. The players accept pain. Theres a sense of order even at the end of a running play with bodies stewn everywhere. When the systems interlock, theres a satisfaction to the game that cant be duplicated. Theres a harmony.”
—Don Delillo (b. 1926)
