Summary of "Proton Hopping In Living Systems."

This review focuses on the two-century old concept of proton hopping. Introduced in 1806 by Grottus, it has evolved into an explanation of great diversity in describing many functions in living systems. It is a process involving water, which expands on the belief that life exists only in the presence of water. This review describes the mechanism of the process as it carries information through water. A focus is initially made on the process in water in the nerve systems. The nature of the process in these systems is described as the passage of proton hopping in living systems. In drug-receptor encounters, proton hopping is initiated, carrying specific information from these specialized encounters. The review continues with an explanation of sleep, arising from an alteration in proton hopping. A similar phenomenon of the effect of general anesthetic agents is described, as they interfere with by proton hopping. Finally, memory functions are addressed in the realm of events carried by proton hopping.

Medical and Biotech [MESH] Definitions

The study of systems, particularly electronic systems, which function after the manner of, in a manner characteristic of, or resembling living systems. Also, the science of applying biological techniques and principles to the design of electronic systems.

A complex of enzymes and PROTON PUMPS located on the inner membrane of the MITOCHONDRIA and in bacterial membranes. The protein complex provides energy in the form of an electrochemical gradient, which may be used by either MITOCHONDRIAL PROTON-TRANSLOCATING ATPASES or BACTERIAL PROTON-TRANSLOCATING ATPASES.

Systems that provide for the maintenance of life in an isolated living chamber through reutilization of the material available, in particular, by means of a cycle wherein exhaled carbon dioxide, urine, and other waste matter are converted chemically or by photosynthesis into oxygen, water, and food. (NASA Thesaurus, 1988)

Energy that is generated by the transfer of protons or electrons across an energy-transducing membrane and that can be used for chemical, osmotic, or mechanical work. Proton-motive force can be generated by a variety of phenomena including the operation of an electron transport chain, illumination of a PURPLE MEMBRANE, and the hydrolysis of ATP by a proton ATPase. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed, p171)

Stable elementary particles having the smallest known positive charge, found in the nuclei of all elements. The proton mass is less than that of a neutron. A proton is the nucleus of the light hydrogen atom, i.e., the hydrogen ion.
