WebSep 9, 2024 · A molecule that binds with an enzyme and undergoes chemical rearrangement is called a substrate. The enzyme “E” combines with the substrate molecule (s) “S” at the active site and forms a temporary enzyme-substrate complex “ES”, where the specific reaction occurs. The modified substrate molecule is the product “P” of the reaction. Web[13] Choose one of the factors that impact reaction rate (enzyme concentration, temperature, or pH) and, in your own words, provide a plausible biological explanation for your experimental results for that factor. Answer: The temperature is the most interesting factor to think about. As the temperature rises so does enzyme activity, think of water, if …

Activation energy is the energy needed to start a chemical reaction. This is illustrated in Figure below. The biochemical reaction shown in the figure requires about three times as much activation energy without the enzyme as it does with the enzyme. WebAug 18, 2024 · August 18, 2024 by Rafi. Answer. The activity of enzymes is affected by the concentration of salt in their environments. Salts lower the freezing point of water, which in turn affects enzyme activity. In cold environments, this decrease in enzyme activity leads to an increase in the rate of chemical reactions. snhu women\\u0027s sweatshirt
