ATP means adenosine triphosphate. It consists of carbon, hydrogen, nitrogen, oxygen, and phorphorus, with the formula C10H16N5O13P3. Structurally it is a nucleoside made up of adenine (a nucleobase) and a ribose sugar molecule, with three phosphate groups. It transfers a phosphate group to another molecule to phosphorylate it (give it energy to get the bonds into a transition state).
It begins with cells, tissues, organs, organ system to organism. There are 11 organ systems that work collectively for an organism to function. Each organ is responsible for a different function and has its own structure. The organism system that consist of the body's outer covering is the integumentary system.
