Detailed explanation-1: -Respiration is a chemical change as new substances like carbon dioxide and water are formed. Also there is change in the mass as glucose is oxidised by oxygen and heat is released. This change is permanent. All these factors conclude that respiration is a chemical change.
Detailed explanation-2: -Respiration is the chemical process of using oxygen to break down glucose to release energy.
Detailed explanation-3: -Cellular respiration or internal respiration is a chemical process in which food molecules are broken down into simpler molecules within the cells and energy is produced.
Detailed explanation-4: -Respiration is a metabolic process that occurs in all organisms. It is a biochemical process that occurs within the cells of organisms. In this process, the energy (ATP-Adenosine triphosphate) is produced by the breakdown of glucose which is further used by cells to perform various functions.
