Answer: Each step in a cascade produces a large number of activated products causing signal amplification as the cascade progresses.
In biology depolarization (British English: Depolarisation) is a change within a cell during which the cell undergoes a shift in electric charge distribution resulting in less negative charge inside the cell . Depolarization is essential to the function of many cells communication between cells and the overall physiology of an organism.
Fri Feb 17 2006 13:30:00 GMT-0500 (Eastern Standard Time) · In biology cell signaling ( cell signalling in British English) or cell – cell communication governs the basic activities of cells and coordinates multiple- cell actions. A signal is an entity that codes or conveys information.Biological processes are complex molecular interactions that involve many signals. The ability of cells to perceive and correctly respond to …
Cellular differentiation is the process in which a cell changes from one cell type to another. Usually the cell changes to a more specialized type. Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types. Differentiation continues in adulthood as adult stem cells …
Sat Nov 10 2001 13:30:00 GMT-0500 (Eastern Standard Time) · Signal transduction is the process by which a chemical or physical signal is transmitted through a cell as a series of molecular events most commonly protein phosphorylation catalyzed by protein kinases which ultimately results in a cellular response .Proteins responsible for detecting stimuli are generally termed receptors although …
In signal processing a signal is a function that conveys information about a phenomenon. In electronics and telecommunications it refers to any time varying voltage current or electromagnetic wave that carries information. A signal may also be defined as an observable change in…
