Allosteric inhibition is the slowing down of enzyme-catalzyed chemical reactions that occur in cells. These metabolic processes are responsible for the proper functioning and maintenance of our bodies’ equilibrium, and allosteric inhibition can help regulate these processes. Essentially, metabolic processes … See more Metabolic processes consist of a series of chemical reactions that produce end products. The key drivers of metabolic processes are … See more To control the speed of metabolic reactions, we have what is called allosteric inhibition. Allosteric inhibitors slow down enzymatic activity by deactivating the enzyme. An allosteric inhibitor is a molecule that binds … See more An example of an allosteric inhibitor is ATP in cellular respiration. This metabolic process operates as a feedback loop. In this loop, downstream products control the speed of upstream … See more Allosteric inhibitors prevent the body from wasting energy to create unnecessary products. Think of a metabolic pathway as an assembly line at a factory. At each station in the … See more WebAllosteric modulators possess properties different from orthosteric ligands. Specifically, allosteric effects are saturable and probe dependent (i.e., the modulator produces different effects for different probes). •.
