1) there is an oxidation of organic substances to the final products of carbon dioxide and water;
2) biological oxidation occurs slowly, sequentially in the process of several reactions, and combustion is a quick process in the form of a single reaction;
3) during combustion, all energy is released in the form of heat, and during biological oxidation, part of the energy is accumulated in ATP molecules in the form of energy of chemical bonds.
