Oxidation
-The process in which a molecule, atom, or ion loses electrons to an oxidant.
Most energy liberated by living matter is derived from the oxidation of organic substances such as carbohydrates, fats, and proteins.
Aerobic oxidation
– takes place in the presence of free oxygen
Anaerobic oxidation
- occurring in the absence of free oxygen. Substance undergoes oxidation either by a loss of hydrogen, as in the oxidation lactic acid to pyruvic acid
Reduction
– brought about either by loss of oxygen or by gain of hydrogen or electrons.
Hydrolysis
– this is the union of substances with one or more molecule of water, forming an unstable “substance-water complex” which is subsequently fragmented.
Condensation
– simple fragments unite with one another to form a more complex compound. The synthesis of complex substances like glycogen and tissue protein is accomplished through this process.
