Enzyme Working Rate Lab Report
Introduction
There are thousands of reactions happen every second in all living cells, and in these reactions, resource, products and enzyme are three most mainly things. In all chemical reactions, there is a activation energy(EA) needed for them. However, if the rate of reactions are too low, they will not be able to sustain lives. In this case, they have enzyme as a protein catalyst. As reaction catalysts, enzymes are proteins that adjust the process by initiating the reaction.
In this case, there are also many elements that influence enzyme working rates. For example, most living things hold a constant PH value. It is reasonable for people to doubt that PH value of surroundings will influence enzyme working rates. Also, livings will also …show more content…
By comparing each of them to others, students will be able to find out an order that if there is any influences and which of these temperatures make the biggest influence.

Experiment A:
There will be six test tubes are set up, which contains one control variable and five different types of substrates: Cyclohexanol, (1, 4) - Cyclohexandiol, (1, 2) - Cyclohexanediol, Catechol, Resourcinol. The darkness of these five test tubes will be the depended variables.
Experiment B:
There will be eleven test tubes are set up, which contains one control variable and ten different types of substrates concentrations : 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100% substrates. The darkness of these five test tubes will be the depended variables.
Experiment C:
There will be five test tubes are set up, which contains one control variable and four different types of enzyme concentrations: 25%, 50%, 75%, 100% substrates concentration. After a period of time. The darkness of these five test tubes will be the depended
