(i) Adenosine triphosphate (ATP) is energy rich molecule and energy is stored in the bonds by which phosphate groups are attached to each other.
(ii) These molecules are stored in the cells as per need.
(iii) Chemically, ATP is a triphosphate molecule formed from Adenosine ribonucteoside.
(iv) It contains a nitrogenous compound adenine,
pentose sugar ribose and three phosphate groups.
(v) As per the need, energy is derived by breaking the phosphate bond of ATP. Hence, ATP is called as the energy currency of the cell.
