Question

why is respiration considered an exothermic reaction ? explain oxidation reduction

Answer 1

Respiration is considered asexothermic 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 isconsidered as exothermic reactionbecause energy is produced during this process.

oxidation:-. , it means the substance that gives away electrons is oxidized. When iron reacts with oxygen it forms a chemical called rust because it has been oxidized (The iron has lost some electrons.) and the oxygen has been reduced (The oxygen has gained some electrons.). Oxidation is the opposite of reduction.

reduction :- Reduction is chemical reaction that involves the gaining of electrons by one of the atoms involved in the reaction.The term refers to the element that accepts electrons, as the oxidation state of the element that gains electrons is lowered. ... In that example, the iron is oxidized and the oxygen is reduced.

Answer 2

Answer:Respiration is considered as an exothermic reaction because in respiration oxidation of glucose takes place which produces large amount of heat energy. This is shown in following chemical equation.(Picture)

An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.
