WebChanges in the concentration of both the enzyme and its substrate will also affect the rate of an enzyme-catalysed reaction. Temperature has a complex effect on the rate of reaction. An increase in temperature increases the kinetic energy of an enzyme and substrate molecules causing them to move more rapidly. WebFollow. That depends on the enzyme, and which salt. I am guessing that you mean some simple salt, like NaCl (and not e.g. morphine sulphate, or serotonine tartrate)? As already mentioned, certain salts can disrupt the protein structure. “ Salting out ” is common practice to purify proteins, by making them less soluble.

WebThe high concentration of salt affects bacterium (Rhizobium)–legume symbiotic nitrogen-fixation potential in many legumes such as soybean, chickpea, pea, faba beans, mung beans, etc. It also decreases the activity of several enzymes such as nitrogenase and phosphatase in legumes and negatively affects the early growth and development of ... WebSalt concentration has to be in its intermediate state for an enzyme to work properly. For instance, if the salt concentration is too high, then the enzyme site will be blocked by the salt ions (Huystee, (1987). Therefore, it will lower the reaction activity rate.
