The ATP molecule is a high energy molecule. When a molecule of ATP breakdown, it produces chemical as well as thermal energy. The type of energy produced is mainly depends on the application for example, if the ATP breaks down to ADP, it produces thermal energy and if couples with a cellular process it produces chemical potential.
Our body needs energy to carry out cellular functions and the energy produced in a form of ATP is taken by cells to perform functions.
Chemical energy --- electrical energy --- light energy
