1. Cellular respiration: In the mitochondria of cells, glucose is oxidized to produce energy in the form of ATP. The overall reaction can be summarized as:
C6H12O6 + 6O2 -> 6CO2 + 6H2O
2. Photosynthesis: In plants, carbon dioxide is reduced to produce glucose using sunlight. The overall reaction can be summarized as:
6CO2 + 6H2O + light energy -> C6H12O6 + 6O2
3. Rusting of iron: When iron is exposed to oxygen and water, it undergoes oxidation to form iron oxide (rust). The overall reaction can be summarized as:
4Fe + 3O2 + 6H2O -> 4Fe(OH)3
4. Metabolism of alcohol: In the liver, alcohol is oxidized to acetaldehyde and then to acetic acid. The overall reaction can be summarized as:
C2H5OH + 2O2 -> CH3CHO + H2O
CH3CHO + O2 -> CH3COOH
5. Electrochemical reactions in batteries: In a battery, redox reactions occur between the electrodes and electrolyte to produce electrical energy. For example, in a lithium-ion battery, the reaction can be summarized as:
LiCoO2 + C6 -> LiC6 + CoO2
These are just a few examples of redox reactions that take place in the body and surroundings.

Redox reactions in the body:
- Respiration (aerobic cellular respiration):
Glucose (C6H12O6) + 6 O2 (g) → 6 CO2 (g) + 6 H2O (l)
- Photosynthesis in plants:
6 CO2 (g) + 6 H2O (l) + light energy → C6H12O6 (s) + 6 O2 (g)
- Digestion of food:
Proteins, carbohydrates, and fats are broken down into smaller molecules, releasing energy
- Metabolism:
Various biochemical reactions that occur in cells, including catabolism (breakdown of molecules) and anabolism (synthesis of molecules)
Redox reactions in the surroundings:
- Corrosion of metals:
Fe (s) + O2 (g) → Fe2O3 (s)
- Burning of fuels:
CH4 (g) + 2 O2 (g) → CO2 (g) + 2 H2O (g)
- Batteries and electrochemical cells:
Redox reactions occur between electrodes to generate electricity
- Electrolysis:
Passing an electric current through a solution to drive a chemical reaction
- Photographic processes:
Exposure of silver salts to light causes redox reactions, resulting in the formation of an image
- Bleaching:
Oxidation of dyes or stains using oxidizing agents like bleach
- Rusting:
Iron exposed to water and oxygen undergoes oxidation, forming iron oxide (rust)
