Through the results of this experiment, some of the factors that effect the rate of a catalysis reaction were able to be explored. As hypothesized, the 6 mL of distilled water did not catalyze with the catalase enzyme because it was not an appropriate substrate and does not produce any products with catalase. This result can be referenced to the lock and key model suggested by Emil Fischer explaining that the enzyme and substrate possess specific complementary geometric properties that would allow the substrate to fit into the active site of the enzyme like a key. Also, the water molecules did not act as appropriate substrates because of the enzymes lack of ability to break down H-O bonds in water and instead affect the peroxide bonds.
The 1.5% hydrogen peroxide concentration reaches a Vmax point of approximately 175 kPa which is also known as its saturation cap, whereas the 3% hydrogen peroxide concentration does not reach a Vmax point as it can be further extrapolated that the rate of reaction will continue to increase linearly past 5 minutes due to its non-hyperbolic relationship within the first 5 minutes. Evidently, as the amount of enzymes remain constant but the number of substrates are increased, the amount of products that are formed will increase initially - since the amount of collisions are increased - but reach a point where there are too many substrates and not enough enzymes, thereby stabilizing a constant speed of reaction until substrate levels are lowered. The enzymes are unaffected by an addition in substrate concentration as their protein structures are not compromised nor encounter any cause for denature.
The 3% hydrogen peroxide concentration’s rate of reaction kept on increasing and did not reach ...

...thesized that the 3 mL distilled water and 3 mL hydrogen peroxide solution would display a stationary relationship which proved to be incorrect because it acted in the same way as the 1.5% concentration in Part B. Furthermore, it was predicted that the copper (II) sulphate and lead (II) nitrate added solutions will have similar slopes after they reach 1/2 Vmaz because they both inhibit the rate of enzyme activity within the solution non-competitively. This hypothesized proved to be somewhat true based on the results from the data. Copper (II) sulphate and lead (II) nitrate behaved similarly but they did not exhibit drastic or significant slopes before the 1/2 Vmaz point. This is due to the immediate effects that altered the sulphur-sulphur cross-bridges and breaking the peptide bonds in the tertiary structure of the enzyme - rendering it ineffective for catalysis.

How Enzymes Affect The Rate Of Chemical Reactions Essay

- Enzymes are biological catalysts - catalysts are substances that increase the rate of chemical reactions without being altered itself. Enzymes are also proteins that fold into complex shapes that allow smaller molecules to fit into them. The place where these substrate molecules fit is called the active site. The active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction. The active site consists of residues that form temporary bonds with the substrate and residues that catalyse a reaction of that substrate....   [tags: Enzyme, Catalysis, Chemical reaction, Metabolism]

Factors That Affect Enzyme Reaction Essay

- There are many factors that affect enzyme reaction rates due to the inherently complex structure that an enzyme possesses. Enzymes are composed of many different proteins that all have their own functional R groups attached. This structure is was enabled enzymes to lower activation energies of almost all reactions and thus makes them crucial to all life processes. Enzymes do this by coming into contact with a substrate. Once in contact, the R groups will either be attracted to or repel the substrate....   [tags: Enzyme, PH, Chemical reaction, Catalysis]

Factors that Affect the Rate of Enzyme Catalysis Essay

- Factors that Affect the Rate of Enzyme Catalysis Enzymes exist in all living things. They are composed of polymers of amino acids and are produced in living cells. Each cell contains several hundred enzymes, which catalyse a vast number of chemical reactions. Enzymes are known as Biological Catalysts as they dramatically increase the rate at which reactions occur within living organisms, without being 'used up' or effecting the reaction in any other way. Enzymes catalysis saves the need for an increase in temperature in order to speed up reactions within living things....   [tags: Papers]

Essay about The Effect Of Concentration On The Reaction Rate Of Enzymes

- This investigation sought to see if an increased pH concentration would affect the reaction rate of enzymes, this investigation was conducted over a 12-day period. The experiment themselves conducted over a 3-5-minute period with 20 second interval intervals. in-between daily measurements in a controlled location with a predetermined temperature of 27°C. The hypothesis was decided based on established theories environmental factors have a key effect on enzyme proficiency, and given the pH concentration solution would affect the enzymes by increasing the speed at which the biochemical reaction occurs, similar to that established by Pieramico O, Dominguez-Munoz JE, etc....   [tags: PH, Enzyme, Acid, Chemical reaction]

Essay about Use of Nickel Catalysis

- There is an overwhelming use of catalysts - a substance that changes the rate of reaction without being consumed by the reaction itself- in various industrial processes. According to certain estimates [cite-wiki10] around 90% of all “commercially produced chemical products involve catalysts at some stage in the process of their manufacture.” Chemical products worth $900 billion were generated by catalytic processes worldwide in 2005 [cite – wiki11]. The close affiliation of the catalysts and the process of catalysis to a variety of industries and the proximity of these industries with consumers raise questions regarding the application of catalysts and their effects on products....   [tags: Economic Benefits, Process]

Essay about Chemical Reactions And The Human Body

- The human body goes through many different reactions and processes that are necessary for humans to live. Chemical reactions by the human body are never seen with the human eye, but it is so vital that these processes are understood. Without this understanding, diseases and disorders can never be resolved or controlled. These processes may be small in size, but have a great deal of impact on the function of the human body. One vital process in the human body observed in chemistry is the idea of chemical kinetics....   [tags: Chemical reaction, Enzyme, Catalysis]

How Enzymes Affect Our Body Essay

- Introduction Our bodies involve and require many different biochemical reactions, which is achieved through the help of enzymes. Enzymes are proteins in our bodies that act as catalyst as they speed up vital biochemical reactions by reducing the “activation energy” needed to get the reaction going. To sustain the biochemistry of life, enzymes maintain temperature inside our living cells balanced and the concentration of reaction molecules. Enzymes are extremely efficient because they remain remarkably unchanged, therefore have the potential to be used over and over again....   [tags: PH, Enzyme, Catalysis, Chemical reaction]

Lab Report on Measuring the Rate of Conversion of Hydrogen Peroxide using Enzyme Catalysis

- Lab Report on Measuring the Rate of Conversion of Hydrogen Peroxide using Enzyme Catalysis In essence, the main objective was to use chemical titration to measure and then calculate the rate of conversion of hydrogen peroxide (H2O2) to water and oxygen by using the enzyme catalase. Other purposes of the lab were; to measure the effects of changes of temperature, pH, enzymes concentration, and substrate concentration on rates of an enzyme. The lab was also an opportunity to see a catalyzed reaction in a controlled experiment....   [tags: Papers]
