NURSING ANM AND GNM

Detailed explanation-1: -Enzymes generally lower activation energy by reducing the energy needed for reactants to come together and react. For example: Enzymes bring reactants together so they don’t have to expend energy moving about until they collide at random.

Detailed explanation-2: -Enzymes allow activation energies to be lowered. Enzymes lower the activation energy necessary to transform a reactant into a product.

Detailed explanation-3: -Enzymes lower the energy of activation by forming an enzyme-substrate complex allowing products of the enzyme reaction to be formed and released. Enzyme catalysed reactions occur at a particular place on the surface of the large enzyme molecule called the active site (as in heterogeneous catalysts).

Detailed explanation-4: -By manipulating the substrates of the reaction, the enzyme can lower the necessary energy needed to make the reaction occur.

Detailed explanation-5: -Temperature: Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction. However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working. pH: Each enzyme has an optimum pH range. Changing the pH outside of this range will slow enzyme activity.
