An illustrative example is the effect of catalysts to speed the decomposition of hydrogen peroxide into water and oxygen: . Acetylcholine is a choline molecule that has been acetylated at the oxygen atom. In biology, tissue is an assembly of similar cells and their extracellular matrix from the same embryonic origin that together carry out a specific function. Although the concept of biology as a single coherent field arose in the 19th century, the biological sciences emerged from traditions of medicine and natural history reaching back to Ayurveda, ancient Egyptian medicine and the works of Aristotle, Theophrastus and Galen in the ancient Greco-Roman world. In biology, signals are mostly chemical in nature, but can also be physical cues such as pressure, voltage, temperature, or light. The discipline involves the application of chemical techniques, analysis, and often small molecules produced through synthetic chemistry, to the study and manipulation of biological systems. The following pictures depict general forms of some of the This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms. 1 In a metabolic pathway, one enzyme takes the product of another enzyme as a substrate.
