ATP works by losing the endmost phosphate group when instructed to do so by an enzyme. This reaction releases a lot of energy, which the organism can then use to build proteins, contact muscles, etc.

ATP works by losing the endmost phosphate group when instructed to do so by an enzyme. This reaction releases a lot of energy, which the organism can then use to build proteins, contact muscles, etc.

Once ATP has released energy, it becomes ADP (adenosine diphosphate), which is a low energy molecule. ADP can be recharged back into ATP by adding a phosphate. This requires energy. These ...

Abnormalities of platelet function in some patients with primary, but sporadic, disorders of hemostasis have been attributed to impaired release of platelet adenosine diphosphate (ADP).
