Oxidation is the loss of hydrogen (H) while reduction is the gain of hydrogen (H). Oxidation and reduction reactions must occur together. The reactant oxidized is the reducing agent. The reactant reduced is the oxidizing agent. These reactions occur in two stages: the “light” stage, consisting of photochemical (i.e., light-capturing) reactions; and the “dark” stage, comprising chemical reactions controlled by enzymes. During the first stage, the energy of light is absorbed and used to drive a series of electron transfers, resulting in the synthesis of ATP and ...Oxidation and reduction occur in tandem. An oxidation reaction strips an electron from an atom in a compound, and the addition of this electron to another compound is a reduction reaction. Because oxidation and reduction usually occur together, these pairs of reactions are called oxidation reduction reactions, or redox reactions.There are several definitions of the oxidation process. Oxidation can be considered as an addition of an oxygen atom to a compound. The opposite of this process is called the reduction in which there is the removal of an electron. Look at the figure-1.
