Why is respiration known as energy releasing process?

Aerobic respiration occurs in the presence of oxygen producing a lot of energy, carbon dioxide and water ... The energy released due to the breakdown of sugar molecule is stored in ATP. Each ATP molecule gives 7200 calories of energy. This energy is stored in the form of phosphate bonds

During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water.

Explanation:

Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
