Test Tube Degrees Celsius
1,267 wordsEnzyme Action: Testing Catalase Activity Enzymes are proteins that serve as catalysts and accelerate chemical reactions in living organisms. Enzymes accomplish this by lowering the energy of activation of the organism it is acting upon, however enzymes will only lower the energy of activation for specific organisms, reducing chaotic chemical reactions. The reaction is carried out in its entirety in the active site of the enzyme. The substrate (organism acted upon), binds itself into the active s...

Rate Of Reaction Bunsen Burner
1,230 wordsInvestigate A Factor Which Affects the Rate Of Fermentation Of Yeast This experiment is investigating one of the factors which affects the rate of fermentation of yeast. Several factors affect the rate of reaction: &# 61656; Increasing the concentration. (See the lock and key theory. ) If the substrate (glucose) is increased, then there would be more keys for the locks, therefore an increase in reactant concentration leads to an increase in reaction rate. &# 61656; The surface area, the bigger t...

Rate Of Reaction Carbon Dioxide
1,229 words... onward sources, from a textbook, encyclopedia, and preliminary work that I have done in class. I have shown my results on a bar chart and a line graph. On the line graph, I have drawn a curve of best-fit. There were no anomalous results. From my results, and my graph, I have found out that as the temperature of the enzymes (yeast in this case) is increased, the rate of reaction speeds up. However, when the temperature reached a certain point, (about 40 degrees Celsius), the enzymes became de...

Three And Four Reaction Rate
859 wordsTitle: Examining Some Properties of the Enzyme -amylase In this experiment a deeper meaning in the catalysts of reactions is studied. Catalysts accelerate chemical reactions without permanently changing the reaction. Enzymes, catalysts in biochemical reactions, are globular proteins which lower the activation energy needed to begin a reaction and therefore increase the rate at which efficient reactions can occur. Proteins (henceforth enzymes) are complex molecules made of amino acids in polypept...

Concentration And Reaction Rate
1,776 wordster> How concentration affects reaction rate. The aim of this investigation is to see how the concentration of a reactant in ratio to the reactor affects the rate of a reaction. When hydrochloric acid and Thiosulphate react together sulphur is liberated this means that as the reaction goes on the solution will become yellow and will change from being transparent to translucent to opaque. The sulphur is formed as a solid but not in the usual precipitation way. Na 2 + S 2 + 2 HCL 2 NaCl+...

Concentration And Reaction Rate
1,782 words... e light intensity the same throughout the entire experiment by working in the shade. Prediction: I predict that as concentration of thiosulphate increases so will reaction rate. Concentration of a reactant affects reaction rate because there are more frequent successful collisions. Assume a person has two chemicals x and y, which react when put together. If all input variables remained constant apart from concentration then fastest reaction rate possible would be to mix (assuming there isnt ...

Rate Of Reaction Reaction Rate
1,069 wordsThe purpose of this experiment is to measure the rates of reaction of the enzyme Alkaline Phosphatase with the substrate p-nitro phenol phosphate under varying conditions. The concentration of both substrate and enzyme were diluted and the inhibitor vanadate was utilized to determine whether or not the reaction is substrate or enzyme dependent and to see what type of inhibition vanadate was involved. A class of proteins called enzymes catalyzes almost every chemical reaction in a cell. Enzymes i...

H 2 O 2 O 2
828 wordsPurpose - The purpose of this lab is to use a chemical titration to measure and them calculate the rate of conversion of hydrogen peroxide (H 2 O 2) to water and oxygen gas using the enzyme catalase. Hypothesis - The rate of enzymatically-catalyzed reactions can be determined by taking time reactions at different time intervals. When the rates are plotted on a graph, the rate of the reaction is the slope of the linear portion of the curve. To determine a rate, any two points on the straight-line...

Source Of Energy Due To The Fact
2,196 wordsOver the past four or five decades, and especially in recent years, there has been a lot of talk among the scientific community and in everyday life about the development of nuclear fusion as an energy source. It seems that the everyday person has some sort of fairy tale image of fusion power in the back of their head. When they hear about dwindling un renewable resources such as coal, oil, and natural gas, they just sort of file it away with the hope that fusion power will come flying down with...

Degrees Celsius Test Tubes
1,993 wordsEffects of Temperature, pH, and Gelatin on Bromelain Introduction Bromelain is an organic catalyst that speeds up the rate of chemical reactions. Bromelain is used in this experiment to catalyze the break down of proteins and is called a proteolytic enzyme. Enzymes enable reactions to occur at a lower temperature and energy levels. This allows many reactions to occur inside living organisms that would otherwise have been impossible to take place. This enzyme is found in fruits, leaves, and stems...

Without them, the rate of the reactions would be so slow as to cause serious, if not fatal, damage. Without enzymes toxins would soon build up and the supply of respiratory substrate would decrease. ? Enzymes are proteins and thus have a specific shape. They are therefore specific in the reactions that they catalyst? one enzyme will react with molecules...
