Factors Affecting Enzyme Activity: This article throws light upon the six factors affecting the enzyme activity. The six factors are:
Analysis Does the action of the catalase change through time? Yes, the action of the enzyme catalase changes over times. I created linear graphs in addition to the segmented statistics graph.
The slope of the lines increases, which means that the speed of the reaction increases exponentially to an extent. If the action of the catalase was the same, the lines would have the same slopes.
They would be the same but with higher statistics. If the difference was additive, then the lines would all be parallel. Based on these data, how does enzyme activity vary with concentration? Because the disks were all soaked in the same amount of catalase, the speed of the reaction increased.
In other words, The number of machines that break down hydrogen peroxide was increased, and the amount of hydrogen peroxide was kept constant. That means the process is faster. In the results, that point was no reached because the line was not vertical. In my results, I found that the one with the most dots started lower than the others but sped up faster.
So, it is proven by the results that the amount of contact and the amount of enzymes affect this experiment greatly by decreasing and then sharply increasing the results.
Based on these data, how does substrate concentration affect enzyme action? There will be more collisions of enzymes and substrate molecules. Then, the reaction will occur faster. The enzymes will speed up because there will be more substrate molecules colliding with them and it is easier to find something to react with.
Based on these data, how does temperature affect enzyme action? When enzymes are heated, the act faster, but if they are heated too much, they will become denatured enzymes. They will not work if they become denatured. We did not do this part of the experiment in class Summarize the general conditions necessary for effective enzyme action.
Are these conditions the same for each enzyme? Why or why not? There must be a standard temperature, maximum surface area, enough enzyme, and enough substrate. Each has a delicate part in the functionality of an enzyme. Each enzyme must have its specified conditions unless the experiment is to kill the enzymes.
Each enzyme is slightly different, but they all need about the same conditions to function and survive.
Conclusion In conclusion, this experiment was successful. The hypothesis was correct. All of the trials with more than one disk was visibly greater than the trial with one disk.Factors Affecting the Rate of Enzyme activity Essay examples.
Length: words ( double-spaced pages) The Effect of Temperature on the Rate of Enzyme Activity Essay examples - The first way is by helping the substrates to bind together. - The Effect of Substrate Concentration on the Rate of Activity of the Enzyme Catalase. The four factors that affect the activity and reaction rate of an enzyme are temperature, pH, enzyme concentration and substrate concentration.
Research Question/Hypothesis: The hypothesis is that when the temperature is higher than 40⁰ C, the enzyme catalysis will increase.
The effect the change of enzyme concentration had on the reaction time of catalase activity can be observed from the graph and table (a). When the enzyme concentration was 25%, the rate of reaction was 22 seconds. However, when the enzyme was at % the reaction occurred within 9 seconds.
There are many factors that contribute to the rate of reaction of an enzyme. Factors include: concentration of the enzyme, temperature, pH level, concentration of the substrate, and inhibitors.
This lab shows the affects these factors have on the rate of reaction between catalase, an enzyme found in potatoes, and hydrogen peroxide, the substrate. For this particular lab, understanding the factors that affect the rate of enzyme activity, there are other ways that can determine the effect of these factors.
Potential Experiment #1: For Part 2 and 3 in this lab, the optimal temperature and pH level were determined during the experiment. The factors that affect catalase activity are temperature, pH level and the concentration of the substrate.
If any of these three factors are changed, the effectiveness of catalase to catalyze the decomposition of hydrogen peroxide will decrease.
