Because ATP stores energy and releases it turning into ADP in the process. This ADP is then converted back to ATP by the cells so that its energy is ready when required, just like a rechargeable battery.
ATP is like a charged battery
When ATP is used, it becomes ADP or Adenine Di-Phosphate. Adding another phosphate will "recharge" ATP.
ADP and ATP are like a battery because they store and release energy for cellular processes. ADP is like a partially charged battery, while ATP is like a fully charged battery ready to provide energy when needed. Just like a battery, the conversion between ADP and ATP allows cells to efficiently use energy for various functions.
There are two phosphate groups in one molecule of ADP.
ADP and a phosphate group are used to create ATP through the process of phosphorylation. When ATP is hydrolyzed, it releases energy, a phosphate group, and ADP, which can then be used to power cellular processes.
Because it can be fully charged by an addition of a phosphate group.
ADP (Adenosine diphosphate) Technically, ATP breaks into ADP and a molecule of inorganic phosphate.
In ATP molecule Adenine is attached to Ribose sugar to which three phosphate molecules are attached. They are high 'energy' bonds formed during biological oxidation of glucose molecule. From ADP you get the ATP molecule. When body needs energy, this ATP is turned into ADP and 'energy' is released. Which is used for various metabolic processes. ADP can turn into AMP in emergency.

When a phosphate group is removed from an ATP molecule, ADP (Adenosine diphosphate) is formed.
Yes, two phosphorus atoms (one in each phosphate group) per ADP molecule.
