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).
The acronym ATP stands for adenosine triphosphate, which is just a description of the molecule's chemical components; an adenine attached to a ribose sugar, and three phosohate groups. What's important here are the phosphates; these are... The ATP molecule basically functions as the power source for the cell. Sometimes it is compared to a battery, which is a pretty fair analogy, but it is more mobile and flexible in its functions than a battery is.
