Chris is studying oxidation and reduction reactions. Which of the following could she use as an example of an oxidation reaction?

A) formation of atp from glucose during respiration, B) formation of carbohydrates from carbon dioxide during photosynthesis, C) formation of oxygen from water molecules during respiration

Oxidation and reduction reaction is also known for the term Redox reaction. The redox reaction is a chemical reaction wherein transfer of electrons between 2 species are involved. It is a type of chemical reaction which the oxidation number of a molecule, or atom, or ion is changed by either obtaining or losing an electron. This is very common and is important to some fundamental functions of life. This reaction occurs in photosynthesis, rusting, and respiration. Therefore the answer is letter D. photosynthesis.
