Catalase Activity Experiment

Catalase activity Experiment objective: To understand whether different concentrations of hydrogen peroxide release different amounts of oxygen when in contact with catalase. Risk Assessment: Hydrogen peroxide is corrosive, irritating the skin and may cause eye damage if exposed to eyes. To prevent this, care must be taken not to touch the skin or goggles during the experiment. Other sharp instruments like females used to cut potatoes are dangerous as sharp faces are touched by the skin and they cut.

The enzyme used is catalase, which decomposes hydrogen peroxide, which releases water and oxygen as bubbles. This foaming is a substance used to measure the reaction rate of catalase. Since any enzyme above this value denatures the enzyme, the optimal caloric activity of the enzyme is shown to be 37 ° C.

In the following experiments, the activity of catalase was measured and plotted over a range of temperatures. The substrate of catalase is hydrogen peroxide, and its decomposition products are water and oxygen. Hydrogen peroxide is a by-product of reactive oxygen species and some biochemical reactions. As hydrogen peroxide accumulates, it becomes toxic, so catalase protects cells from oxidative damage. A. Temperature is a measure of the kinetic energy of molecules in the system. As the temperature rises, the kinetic energy of the enzyme and hence the number of random collisions between the enzyme and the substrate increases per unit time. As the collision frequency increases, the likelihood that the enzyme will collide with the matrix in the correct direction also increases (ie the matrix is ​​suitable for the active site). Therefore, the reaction rate increases with increasing temperature until the optimum temperature is reached.
