regulation definition biology

… For that reason, some amount of regulation is required to ensure efficiency and prevent the waste of any excess resources. Leave a Comment Cancel reply. Regulation is the management of complex systems according to a set of rules and trends. In systems theory, these types of rules exist in various fields of biology and society, but the term has slightly different meanings according to context. 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. Upregulation of endothelial cell adhesion molecules, such as selectins, initiates neutrophil tethering. The act of regulating or the state of being regulated. To do this they sometimes tether RNA polymerase to the promoter. The binding of specific protein (activator) is required for transcription to begin. The process of turning on a gene to produce RNA and protein is called gene … Osmoregulation is a process that regulates the osmotic pressure of fluids and electrolytic balance in organisms. Negative Regulation The binding of a specific protein (repressor) inhibits transcription from occurring. Gene regulation ensures that the appropriate genes are expressed at the proper times. At the centre of a thermostat is a bimetallic strip that responds to temperature changes. The word homeostasis derives from Greek, with home meaning “similar,” and stasis, meaning “stable.”When used as an adjective, it is homeostatic. All cells control or regulate the synthesis of proteins from information encoded in their DNA. For a cell to function properly, necessary proteins must be synthesized at the proper time. During this process, the concentration of hormones like insulin increases when the blood sugar level increases in order to bring the level back to normal.

Ø When the regulatory enzyme reaction is slowed, all subsequent enzymes operate … Sports The standard playing period for a timed game, prior to … For example, there is an increase in uterine oxytocin receptors in the third trimester of pregnancy, promoting the contraction of the smooth muscle of the uterus. Another word for regulation. Negative Regulation; Conclusion; Definition of Arabinose Operon. Search. DNA bound activators can regulate transcription by helping with ignition. Topic: Regulation of Internal Environment (Homeostasis) Homeostasis is defined as the maintenance of a steady internal environment. For example: in biology, gene regulation and metabolic regulation allow living organisms to adapt to their environment and maintain homeostasis; in government, typically … C. Carmona-Rivera, M.J. Kaplan, in Encyclopedia of Cell Biology, 2016. Ø Feedback inhibition is a specific type of allosteric enzymatic activity regulation mechanism in cells.

Biology and Regulation: Considerations for Self Regulation Development. For example, imagine if you owned a bakery and one of your new employees used up all the flour, sugar and … The two types of gene expression regulation are: (1) Negative Regulation and (2) Positive Regulation. The strip expands under warmer conditions and contracts under cooler conditions to either disrupt or complete an electric circuit. Define the term regulation as it applies to genes. | Meaning, pronunciation, translations and examples Medical Author: William C. Shiel Jr., MD, FACP, FACR; Downregulation: An decrease in the number of receptors on the surface of target cells, making the cells less sensitive to a hormone or another agent. Also called executive order. … Hide. Osmoregulation Definition “Osmoregulation is the process by which an organism regulates the water and electrolytic balance in its body to maintain homeostasis.” What is Osmoregulation? The term is considered by some to be misleading in that the word element-stasis implies a static or fixed … adj., adj homeostat´ic. Tethering and Rolling. Alternative Title: osmotic regulation. Gene regulation is the process of turning genes on and off. 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.
