An oxidation reaction involves the loss of electrons from a molecule, atom, or ion. In microbial metabolism, these reactions are essential for energy production.
congrats on reading the definition of oxidation reaction. now let's actually learn it.
Oxidation reactions often occur in tandem with reduction reactions, collectively known as redox reactions.
The electron transport chain in cellular respiration relies heavily on oxidation reactions to produce ATP.
Common oxidizing agents in microbial metabolism include oxygen and NAD+.
Oxidation reactions can produce reactive oxygen species (ROS), which can damage cellular components if not regulated.
Enzymes like oxidases and dehydrogenases facilitate oxidation reactions in microbial cells.
