The capacity for collections of biochemical reactions to respond in a switch-like, or all-or-none, manner is of fundamental significance in biological signal processing, and has been widely observed in many different signalling contexts [1–3].Biochemical switch-like responses can exist as two distinct types [4,5]: …
WebJan 11, 2024 · Eating patterns in modern societies often preclude the metabolic switch from utilization of glucose to ketones as a cellular energy source. In this Review, Mattson and colleagues discuss how ... 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.
