Question
How does REDOX Reactions affect our everyday lives?
Redox reactions include all chemical processes in which atoms have their oxidation state changed, either by oxidation or reduction (hence the name). Oxidation is the loss of an electron; reduction is the uptake of an electron. Astrobiologists are interested because most biological energy is stored and released by redox reactions, including photosynthesis and respiration. Metabolism, which is a fundamental property of life, involves many redox reactions as part of the extraction of energy from the environment for use by living things. Without complex redox reactions, you would not have an everyday life. David Morrison
