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