Energy is released during the oxidation of compounds in respiration. How is this energy stored and released as and when it is needed?

(N/A) During respiration,energy-rich compounds like sugars,lipids,and proteins undergo oxidation. The energy released during these chemical reactions is not released all at once but in a controlled,step-by-step manner.
As these organic molecules are broken down,the released energy is captured by electron carriers and used to synthesize $ATP$ (Adenosine Triphosphate) molecules. $ATP$ acts as the primary energy currency of the cell.
When the cell requires energy for metabolic processes,such as biosynthesis,active transport,or mechanical work,the terminal phosphate bond of $ATP$ is hydrolyzed,releasing the stored energy for immediate use.
