WebThe mechanism of enzymatic action. An enzyme attracts substrates to its active site, catalyzes the chemical reaction by which products are formed, and then allows the products to dissociate (separate from the enzyme surface). The combination formed by an enzyme and its substrates is called the enzyme–substrate complex. WebThe general properties of enzyme include the following characteristics: Enzymes initiate and accelerate the reaction. The activity of an enzyme is pH-specific. Enzymes can catalyze reactions in a forward and reverse manner, but do not decide the direction of the biochemical pathway. ask yakar 11
