Hint: Adenosine triphosphate(ATP) is the molecule that stores and transfers energy in all the living cells. It has its energy stored in the third phosphate group. When a phosphate group is separated from ATP, it forms a bi product called ADP(Adenosine diphosphate) along with the release of energy.

Complete Answer:
- ATP is produced by ATP synthase enzyme which is responsible for the conversion of phosphates and ADP to ATP.
- ATP synthase enzyme is usually found in mitochondria. It is found in chloroplast in the plant cells. In ATP, high energy is stored in the form phosphate bonds. To carry out other functionalities, the cell needs energy.
- This energy is released by ATP by breaking its bond with the third phosphate group and forming a bi product ADP. ATP plays an important role in the transportation of macromolecules such as lipids and proteins in and out of the cell.

Hence the correct option is (a) Energy.

Note: ATP is known as the ‘energy currency of the cell’ and mitochondria which stores these ATP in the form of chemical energy is termed as ‘powerhouse of the cell’. The process of conversion of ATP to ADP is called Hydrolysis and the process of conversion of ADP to ATP is called chemiosmotic phosphorylation.
