How Do I Change My Password on Yahoo! By Steve Gregory. Although Yahoo does not offer a way to recover your account password, the company does provide a Password Helper service to help you reset your password. You can use the service for a relatively benign reason. Documenting Business Use-Case Realizations. Activity diagrams give focus to the workflow, while sequence diagrams give focus to the handling of business entities. Activity diagrams and sequence diagrams could be used as complementary techniques, where a sequence diagram shows what happens in an activity state.
Enzymes are proteinaceous catalysts, which speed up the rate of a biochemical reaction. They reduce the activation energy that is essential for starting any type of chemical reaction. With a low energy requirement for activation, the reaction takes place faster. The overall performance of an enzyme depends on various factors, such as temperature, pH, cofactors, activators, and inhibitors.
You might have a fair idea regarding the effect of pH on enzymes. But why and how does pH and temperature affect enzymes?
Consider a case when the reaction is adjusted at a pH level different from the optimum value. Over here, the rate of reaction or the activity of enzymes will not be the same as the previous one. At times, you will notice that there is no reaction at all. This occurs when there are changes in the structure of the active site and the substrate. Hence, for the chemical reaction to take place, you need to adjust the pH of the solution in such a way that it is suitable for both, the enzyme and the substrate. This way, the effect of pH on enzyme activity can be studied practically.
