list 5 chemical reaction which support life

Answer 1

Chemical reactions which support life

1.Photosynthesis:This is the reaction by which green plants take oxygen and carbondioxide from the atmosphere and prepare their food.
                         6CO2+ 6H2O + Light →C6H12O6 + 6O2
2.Respiration : The chemical process by which breakdown of food takes place to release energy[In the form of ATP, which is used by the cells for their metabolic activities.
                      C6H12O6 + 6O2 →6CO2 + 6H2O +energy
3.Combustion: It is a chemical reaction. combustion is seen in the burning of propane in  stoves and gas burners
                     C3H8 +5O2→4H2O + 3CO2 +Energy
4​.Digestion: The process by which our food breaks down into smaller particles and releases energy for various metabolic activities.It involves decomposition as well as oxidation of food particles.
                  C12H22O11 + H2O  →    C6H12O6 + C6H12O6


5.Acid base neutralisation reaction: Here the acids in body react with bases to form salt and water
                         HCl+ NaOH  →    NaCl + H2O
