Answer:
Redox reaction occur along the two electron transport chains.
Step-by-step explanation:
- In redox type of chemical reaction, the oxidation state of the atoms is changed due to the transfer of electrons between the chemical reactants.
- One of the species is oxidized whereas the next species are reduced. The electron gaining species undergoes reduction but the species that donate the electron gets oxidized.
- In a redox reaction, the process of oxidation and reduction occurs simultaneously.
- In redox reaction, oxidation of one species means the reduction of the next species that shares electrons.
