Explanation:
All the cells in a living organism undergo cellular respiration to extract the chemical energy from food molecules and convert it into  usable energy form of ATP. 
The food molecules having chemical energy are oxidized to produce energy that can be used for all  cellular metabolism processes and other energetic reactions required for life
Later on this ATP's energy is used for building new molecules and transporting materials. 
Hence, given statement is true
