Bioreaction is a term used in biology and biotechnology to describe a chemical reaction that takes place within living organisms or in the presence of biological molecules. Synonyms for bioreaction include biochemical reaction, biological process, metabolic activity, enzyme catalysis, cellular metabolism, and biocatalysis. These terms all refer to the same basic concept of chemical reactions involving living organisms or biochemical molecules. Bioreactions are vital to many biological processes, including energy production, digestion, and cellular growth and reproduction. By studying and understanding the mechanics of bioreactions, scientists and researchers can gain insight into the workings of living systems and develop new treatments and technologies for a variety of applications.
