Answer :
Oxidation is the loss of electrons.
Reduction is the gain of electrons.
The compound that became reduced acts as the oxidizing agent.
The compound that became oxidized acts as the reducing agent.
The measure of a compounds likeliness to gain or lose an electron is its electrochemical potential (E value).
A common electron carrier we will use a lot in this class is NAD⁺ when it is in the oxidized state and NADH when it is in the reduced state.
Explanation :
Redox reaction or Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.
Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. In this, oxidation state of an element increases. Or we can say that in oxidation, the loss of electrons takes place.
Reduction reaction : It is defined as the reaction in which a substance gains electrons. In this, oxidation state of an element decreases. Or we can say that in reduction, the gain of electrons takes place.
Reducing agent : It is defined as the agent which helps the other substance to reduce and itself gets oxidized.
Oxidizing agent : It is defined as the agent which helps the other substance to oxidize and itself gets reduced.
Electrochemical potential : It is defined as the measurement of the potential difference between two half cells.
Electron carrier : The molecules that are capable of accepting 1 or 2 electrons from one molecule and donating to another molecule in the process of electron transport.
There are two important electron carriers:
Nicotinamide adenine dinucleotide (NAD⁺ in its oxidized form and NADH in its reduced form).
Flavin adenine dinucleotide (FAD)
