Enzymes

Introduction: Enzymes are an important part of all metabolic reactions in the body. They are catalytic proteins that increase the reaction rate without being consumed by the process (Campbell 96). This allows the enzyme to be used again for other reactions. The enzyme promotes the reaction by reducing the activation energy. Activation energy is the energy required to break chemical bonds between reactants and combine with other substances to form products (Campbell 100). In this experiment, the enzyme used was acidic phosphate (ACP) and the substrate was p-nitrophenyl phosphate.

Enzyme inhibitors are molecules that reduce or eliminate the activity of enzymes and enzyme activators are molecules that increase the rate of enzyme catalysis. These interactions can be reversible (ie, removal of the inhibitor to restore enzyme activity) or irreversible (ie, the inhibitor permanently deactivates the enzyme). Traditional reversible enzyme inhibitors are classified as competitive, noncompetitive or noncompetitive based on their effect on Km and Vmax. These different effects result from combinations of inhibitors and enzyme E, enzyme-substrate complex ES or both, respectively. The division of these classes arises from problems in their derivation and leads to the need to use two different coupling constants for the binding event. The combination of inhibitors and their effect on enzyme activity are two different things, another problem that can not be recognized with conventional equations.

Enzymes are proteins that catalyze biochemical reactions. Each enzyme has a specific function, and the enzyme acts on one kind of substrate - this substance binds to the active site of the enzyme. The shape of the enzyme must match the shape of the matrix in order to react. Temperature affects the shape of the enzyme. For example, when enzymes are active at moderate temperatures, higher or lower temperatures may affect their ability to act on substances. Before testing the enzymatic activity of certain substances, you need to create a water bath to set the reaction temperature. You will need three larger containers than the beakers and tubes used for the reaction. Filling the first two thirds with water at room temperature should be about 37 degrees Celsius. Fill the second two thirds with water and add ice; the bath temperature should be around 5 degrees Celsius. Put 2/3 water in the third container and place it on a hot plate or Bunsen burner and boil
