Enzymes are biological catalysts, they have optimum pH values and temperatures, their activity is greatest while in optimum. Enzymes are also proteins, if the shape of an enzyme changes, it would no longer work. Enzymes are substances that fasten the chemical reactions in the human body. Enzymes are proteins that make up shapes in order to allow smaller molecules to fit into them to increase the chemical reaction rate. Although enzymes are made by living thing, enzymes are not alive themselves.
Below is an example of how the smaller molecules fit into an enzyme:
Enzymes may change their shape if they are effected by high temperature or high pH and after having their form changed the enzymes would not be able to …show more content…
The measuring tube was cleaned for the second pH buffer which was pH 4, two milliliters of hydrogen peroxide was poured into the measuring tube, then three drops of pH 4 buffer, lastly two milliliters of catalase was added to the mixture and was stirred once for two seconds, after waiting for one minute for the froth to produce, the amount of froth after one minute was seventeen millimeters. For the third part of the experiment a pH 6 buffer was used, after the measuring tube being cleaned, two milliliters of hydrogen peroxide, three drops of pH 6 buffer and two milliliters of catalase was added, the mixture was stirred once and for two seconds the froth produced was measured with a ruler after one minute, the amount of froth produced was thirty millimeters. For the fourth part a pH buffer of 8 was used, the measuring tube that was going to be used for this part was cleaned, two milliliters of hydrogen peroxide, three drops of pH 8 buffer and two milliliters of catalase was used, the concoction was stirred once for two seconds, and the froth was measured after one minute, the froth produced was fifty-three millimeters. For the last part pH 10 buffer was used, the measuring tube was cleaned, two milliliters of hydrogen peroxide, three drops of pH 10 buffer and two milliliters of catalase was used, the solution was stirred once for two seconds, after waiting for one minute the froth produced was seventy-six
