Biochemical switch

A series of biochemical switches control transitions between and within the various phases of the cell cycle. The cell cycle is a series of complex, ordered, sequential events that control how a single cell divides into two cells, and involves several different phases. The phases include the G1 and G2 … See more Many biological circuits produce complex outputs by exploiting one or more feedback loops. In a sequence of biochemical events, feedback would refer to a downstream element in the sequence (B in the adjacent image) … See more An "all-or-none" response to a stimulus is termed ultrasensitivity. In other words, a very small change in stimulus causes a very large change … See more The G1/S transition, more commonly known as the Start checkpoint in budding yeast (the restriction point in other organisms) … See more G2 is commenced by E2F-mediated transcription of cyclin A, which forms the cyclin A-Cdk2 complex. In order to proceed into … See more Positive and negative feedback loops do not always operate distinctly. In the mechanism of biochemical switches, they work together to create a flexible system. For example, according to Pfeuty & Kaneko (2009), to overcome a drawback in biochemical … See more Bistability implies hysteresis, and hysteresis implies multistability. Multistability indicates the presence of two or more stable states for a given input. Therefore, bistability is the ability of a system to exist in two steady states. In other words, there … See more In the transition from metaphase to anaphase, it is crucial that sister chromatids are properly and simultaneously … See more WebRegulation of ERK activation may be a key biochemical switch responsible for terminal differentiation of components of the crypt-villus unit. ... containing numerous mucous granules and termed HT29-18-N2 was studied to determine the cellular mechanisms underlying a switch to the differentiated phenotype.
