Respiration is a chemical process that involves converting oxygen and glucose into energy, carbon dioxide, and water. It is a metabolic change that provides the necessary energy for cellular functions in organisms.

because they become oxidized and reduced when glucose is broken down in photosynthesis and cellular respiration.
Physical change of the paint, not the door.
it is a chemical change
ATP can be converted into heat energy through cellular respiration. During cellular respiration, the energy stored in ATP is released as the chemical bonds in ATP are broken down, resulting in the production of heat as a byproduct of this process.
Crushing charcoal into powder is a physical change, as it alters the size and shape of the charcoal without changing its chemical composition.
