Cellular respiration is used to create usable energy from the foods that living things eat. It's important to know that the reactions involved in cellular respiration are catabolic, meaning they break down molecules into smaller ones.
Cells do cellular respiration to extract energy from the bonds of glucose and other food molecules. Cells can store the extracted energy in the form of ATP (adenosine triphosphate). Hope this helps please give five stars and Brainly
