Web14 de jan. de 2024 · Neopyropia yezoensis is an economically important marine crop that can survive dehydrating conditions when nets are lifted from seawater. During this process, production of oxygen radicals and the resulting up-regulation of antioxidant enzymes mediated by the abscisic acid (ABA) signaling pathway played an important role. … WebThere are many factors that can regulate enzyme activity, including temperature, activators, pH levels, and inhibitors. Temperature: That's a good one. Proteins change shape as temperatures change. Because so …
WebEnzymes can be regulated by other molecules that either increase or reduce their activity. Molecules that increase the activity of an enzyme are called activators, while molecules that decrease the activity of an enzyme are called inhibitors. WebEnzyme activity can be regulated by temperature and pH. With temperature, the rate of an enzymatic reaction increases with increasing temperature. Each enzyme has an optimal temperature at which its reaction rate is greatest. With pH, enzymes also have an optimal pH at which it is most active. The optimal pH values for most enzymes are 6-8.
