Respiration is physical as well as chemical process . Explain.

Answer 1

Respiration is physical as well as chemical process

• Respiration is the biochemical process in which the cells of an organism obtain energy by combining oxygen and glucose, resulting in the release of carbon dioxide, water, and ATP (the currency of energy in cells)Glucose is oxidised to CO2 and H2O (along with release of energy) at the cells by the oxygen from air we breathe in. Since glucose is converted into new products with different composition, respiration is a chemical change.
