Enzymes are biological catalysts‚ large protein proteins that have a very specific three-dimensional shape which makes them highly specific and only work on one or a few similar chemical reactions. Enzymes themselves are not consumed in the reaction‚ but they help attract substrates into correct position to undergo chemical reaction. Enzymes greatly speed up the rate of biological reactions by lowering the energy of activation. To get a sense of the speed and efficiency of enzymes‚ substrates can

Enzyme Lab Using Jello INTRODUCTION: Enzymes are known as protein catalysts. The name protein catalyst suggests that most enzymes are made of proteins. A catalyst is a substance that speeds up chemical reactions without being consumed in the process. (Giuseppe‚ M 2002‚ p.69). After a reaction has been catalyzed‚ the catalyst can be used again to catalyze the same reaction. Enzymes reduce the activation energy (minimal energy) it takes for a reaction to take place. Enzymes can either catabolize

The experimental results were different from the hypothesis because while the enzyme appeared to not work as well‚ I expected a more significant change. Most of the time‚ there was only a millimeter of difference of the foam between the two samples while I expected a greater difference such as 10 millimeters. Enzymes speed up chemical reactions and at the active site‚ a substrate can be broken down or two substrates can form a larger molecule. Hydrogen peroxide is broken down by peroxidase into water

The reason why I think this could be a limitation is because each solution has an extreme acidic pH level like 1 or 2. As a result‚ I speculate the supreme acidity of the solution could negatively affect the pH measurer that could make it lose the originality to measure the right pH level for later product. Hence‚ it is crucial to have the pH measurer calibrated in a buffer solution so that the measurement can have a high accuracy overall. Thirdly‚ when measuring the

Abstract: Enzymes‚ molecules that speed up chemical reactions‚ are specific to one substrate. In this experiment the substrate hydrogen peroxide and the enzyme catalase will be used. The higher the concentration of potato extract‚ or catalase‚ the faster the reaction and the more substrate present will result in a decrease in the time of the reaction. The amount of concentrations of enzymes and substrates are changed to determine if the reaction is further catalyzed by a greater concentration of
