ATP is always alternationg between ADP and ATP. ADP is a simpler form of ATP, which is made up of two phosphate groups instead of three. ATP is usually used in mitochondrial cycles such as glycolysis and oxidative phosphorylation, and is usually made from ADP during these cycles. So, my first guess would be that ADP is like the 'dormant' stage of ATP, meaning it is in that form when it is not being directly used to 'power' cycles. Therefore, there is no way to 'measure' their 'life span', they are simply being made and broken down according to cell functions.
ATP is an active molecule in cellular processes.

The chief energy currency all cells use is a molecule called ATP. ATP is the main energy source that cells use for most of their work adenosine.
Approximately 19 ATP molecules can be generated from the metabolism of a molecule of glycerol through the process of glycolysis and the citric acid cycle.
Energy is released from an ATP molecule through a process called hydrolysis, where a phosphate group is removed from the ATP molecule, breaking a high-energy bond and releasing energy that can be used by the cell for various biological processes.
By losing the last molecule and turning into ADP
Last I heard, the energy molecule for humans is ATP, adenosine triphosphate. I don't think that other living things such as plants have ATP. They do photosynthesis. But regarding humans, ATP is taught to be the energy molecule.
There is only one type of ATP and it is a molecule all of its own.
ATP is an active molecule in cellular processes.
ATP
ATP or adenosine triphosphate, is involved in energy transfer.

No, cells do not store ATP for long periods of time as ATP is a high-energy molecule that is constantly being used and regenerated within cells. Cells produce ATP as needed through processes like glycolysis and cellular respiration.
ATP (the molecule) is not considered to be a currency.
Atp
ADP
The phosphate group is the part of the ATP molecule that breaks free when ATP is used for energy, converting ATP to ADP (adenosine diphosphate). This release of the phosphate group provides the energy needed for cellular processes.
