Answer:
Respiration is considered as exothermic reaction because energy is released in this process. Glucose combines with oxygen present in our cells to form carbon dioxide and water along with energy. Respiration is considered as exothermic reaction because energy is produced during this process.
Oxidation is the loss of electrons during a reaction by a molecules, atom or ion. ... The opposite process is called reduction , which occurs when there is a gain of electrons or the oxidation state of an atom, molecule, or ion decreases.
