WebEnzymes are folded into complex 3D shapes that allow smaller molecules to fit into them. The place where these molecules fit is called the active site. In the lock and key … WebThe active site of an enzyme also creates an ideal environment, such as a slightly acidic or non-polar environment, for the reaction to occur. The enzyme will always return to its original state at the completion of the reaction. One of the important properties of enzymes is that they remain ultimately unchanged by the reactions they catalyze.
WebThe difference between zymogens and the activated enzymes lies in the fact that the active site for catalysis of the zymogens is distorted. As a result, the substrate … WebThe amino acids in the active site of enzymes play two roles, and sometimes those roles overlap. ... Note that the energy difference between the substrate and the product is not changed by the enzyme. In all chemical reactions, there is an initial input of energy that is required before the reaction can occur. If this initial energy requirement ...
