ATP is the abbreviated term used to refer to a chemical
consists of adenosine and three phosphate groups. It is called triphosphate
because of it includes three phosphate
groups and has the chemical formula: C10H8N4O2NH2(OH)2(PO3H)3H
ATP plays an important role in muscle
actions (contraction and relaxation), as follows:
filaments) include an enzyme called ATPase that splits ATP into
ADP (adenosine diphosphate) and a phosphate group.
diphosphate (ADP) + energy + inorganic Phosphate
Very many molecules
of ATP are split in this way
with every movement of every muscle. ATP cannot be stored, but is
used as it is produced by the body. Each ATP molecule is recycled
3000 times during a single day.
The opposite to the above process is:
Adenosine diphosphate (ADP) + inorganic Phosphate + energy _-->_ ATP
