In general, regulation means the process of regulating (or) regularising some process or functions. Operon regulation can be either negative or positive by induction or repression. Enzymes are effective and reusable, and will continue certain chemical processes if there is additional substrate to work with.

The term is considered by some to be misleading in that the word element-stasis implies a static or fixed … DNA bound repressors often act to prevent RNA polymerase from … Homeostasis is an organism’s process of maintaining a stable internal environment suitable for sustaining life. Selectins are translocated to the apical membrane of the … Osmoregulation is a process that regulates the osmotic pressure of fluids and electrolytic balance in organisms. C. Carmona-Rivera, M.J. Kaplan, in Encyclopedia of Cell Biology, 2016. 4. Repression; Derepression; Attenuation; Conclusion; Definition . Water Quality Analysis by Membrane Filter (MF) Technique. This upregulation occurs through mobilization of P-selectins from Weibel–Palade bodies and by upregulation of de novo synthesis of E-selectins. Regulatory biology synonyms, Regulatory biology pronunciation, Regulatory biology translation, English dictionary definition of Regulatory biology. The association and dissociation of the repressor protein strongly depend upon the tryptophan level in the … Regulation. In addition to respiratory centres, there are certain receptors also that can detect changes in CO 2 and H … Osmoregulation. For those … Local Regulation is a means of controlling functioning (i.e., homeostasis) in only a very small portion of a body typically as involving detection of chemical signals and modification of immediately local chemistry. It is highly sensitive to CO 2 and hydrogen ions.Increase in CO 2 and H + ions activate this centre, which in turn signals the rhythm centre to adjust the respiratory process and eliminate these substances.. The two types of gene expression regulation are: (1) Negative Regulation and (2) Positive Regulation. For example, imagine if you owned a bakery and one of your new employees used up all the flour, sugar and … When looking at self regulation, I believe in using what’s called a “top down approach”. See also balance and equilibrium. Gene regulation is accomplished by a variety of mechanisms including chemically modifying genes and using regulatory … Define the term regulation as it applies to genes. Homeostasis. A gene is a small piece of genetic material written in a code and called DNA. Local Regulation ∞ generated and posted on 2016.12.23 ∞ Chemical signals generated in the immediate environment of a cell along with responses affecting that immediate environment. Biology Article. DNA bound activators can regulate transcription by helping with ignition. Homeostasis Definition “Homeostasis is the state of steady internal chemical and physical conditions maintained by living systems.” Table of Contents. The big picture of eukaryotic gene regulation. Biology, SS 3 Week: 1. If you're seeing this message, it means we're having trouble loading external resources on our website. To accomplish this, cells use a variety of chemical “signal … Arabinose operon can define as the system which carries the number of genes like a regulatory, promoter, operator, inducer and structural genes for the breakdown of L-Arabinose into Xylulose phosphate. Ø When the regulatory enzyme reaction is slowed, all subsequent enzymes operate … Upregulation: An increase in the number of receptors on the surface of target cells, making the cells more sensitive to a hormone or another agent. The act of regulating or the state of being regulated. Embryology The capacity of an embryo to continue normal development following injury to or alteration of a structure. Cell Cycle- Definition, Phases, Regulation and Checkpoints; Categories Molecular Biology Tags Regulation, Regulation of Translation In Eukaryotes, Translation in Eukaryotes Post navigation. Medical definition of downregulation: the process of reducing or suppressing a response to a stimulus; specifically : reduction in a cellular response to a molecule (as insulin) due to a decrease in the number of receptors on the cell surface. Another word for regulation. Ø Feedback inhibition is a specific type of allosteric enzymatic activity regulation mechanism in cells. For example, insulin receptors may be downregulated in type 2 diabetes. Name Email Website. Osmoregulation, in biology, maintenance by an organism of an internal balance between water and dissolved materials regardless of environmental conditions. For example: in biology, gene regulation and metabolic regulation allow living organisms to adapt to their environment and maintain homeostasis; in government, typically … pH regulation (biology), published June 2014: Download PDF Get Adobe Acrobat Reader ; Content. Meaning; Explanation; Breakdown; Body System; Examples; Homeostasis Meaning and Etymology. For that reason, some amount of regulation is required to ensure efficiency and prevent the waste of any excess resources. Ø Feedback inhibition definition: in some multi-enzyme pathways, the regulatory enzyme is specifically inhibited by the end product of the pathway whenever the concentration of the end product exceeds the cell’s requirements. Search. The conversion of arabinose into xylulose phosphate is carried out by the structural genes ara-B, A and D which transcribes mRNA by … Gene regulation is the process of turning genes on and off. Organisms need to be able to stop cell division when the cell in question is damaged, or when there isn’t enough food to support new growth; they must also be able to start up cell division when growth or wound healing are needed.
