The true measure of an appraisalâwhether a gem, jewelry, or a watchâis a combination of sophisticated laboratory technology, and expertise in interpreting the test results.
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. The reaction product is adenosine diphosphate (ADP), and the phosphate group either ends up as orthophosphate (HPO 4) or attached to another molecule (e.g. an alcohol).
Confidence votes 7.7K. ATP is split into ADP and a free phosphate group by an ATPase, which is an enzyme that catalyzes the hydrolysis of the bond linking the terminal phosphate to the rest of the ATP molecule. The breaking of this bond releases a large packet of energy, which can be used for cellular purposes.
