ANSWER: Cellular respiration is a set of metabolic reactions and processes that take place in the cell of organism to convert chemical energy from oxygen molecules or nutrients into ATP, and then release waste products. The reaction involved in this type are of catabolic reactions, which break larger molceules into smalle ones, releasing energy because weak high energy bonds, in particular molecular oxygen, are replaced by stronger bonds in the products. Cellular respiration is also combustion respiration, it clearly does not resemble one when it occurs in the living cell because of the slow, controlled release of energy dfrom the series of reactions.
