The reactant oxidized and reduced in a reaction that occurred, “when someone exercises vigorously, pyruvate is converted to lactate in cells through the redox reaction”. Introduction: The oxidation and reduction reaction always occurs together in a chemical reaction called “redox reaction” (or oxidation-reduction reaction). Redox reaction is a “reaction of transferring electrons”. Redox reaction contains features of oxidation number change: Oxidation: losing electron and increasing oxidation number and in reduction: gaining electron and decreasing oxidation number.
