Question

Most common chemical reaction for breakdown of molecules are oxidation- reduction . Explain.

Answer 1

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

Answer 2

Answer:

Oxidising-reducing reactions are some of the most common chemical means to break down molecules

Explanation:

Oxidising-reducing reactions are some of the most common chemical means to break down molecules. For this, many organisms use oxygen sourced from outside the body. The process of acquiring oxygen from outside the body, and to use it in the process of break down of food sources for cellular needs, is what we call respiration:))
