Answer:
Redox is a type of chemical reaction in which the oxidation states of atoms are changed. Redox reactions are characterized by the actual or formal transfer of electrons between chemical species, most often with one species undergoing oxidation while another species undergoes reduction

Redox is a type of chemical reaction in which the oxidation states of atoms are changed. Redox reactions are characterized by the actual or formal transfer of electrons between chemical species, most often with one species undergoing oxidation while another species undergoes reduction.
Biology
The act of decreasing or reducing something. ... Any process in which electrons are added to an atom or ion (as by removing oxygen or adding hydrogen); always occurs accompanied by oxidation of the reducing agent. The act of reducing complexity.
Steps
STEP 1: Write a skeleton equation for the reaction. ...
STEP 2: Assign oxidation numbers to atoms on both sides of the equation. ...
STEP 3: Determine which atoms are oxidized and which are reduced.
STEP 4: Divide the reaction into oxidation and reduction half-reactions and balance these half-reactions one at a time.
Rules
There are rules for assigning oxidation numbers to atoms. Oxidation is an increase in oxidation number (loss of electrons); reduction is a decrease in oxidation number (gain of electrons).
Water-oxidation catalysts mediate the four-electron, four-proton oxidation of water to dioxygen. The energy of the resulting electrons and protons released during water oxidation is then stored as the biological equivalent of hydrogen. ...
