Catalase lab report

This reaction is caused by catalase, an enzyme within the potato. If the cells did not break down the hydrogen peroxide, they would be poisoned and die.

Investigation: Enzymes

In addition, your access to Education. The name of the enzyme is catalase; it speeds up a reaction which breaks down hydrogen peroxide, Catalase lab report toxic chemical, into 2 harmless substances--water and oxygen. Introduction This lab covered the measuring of the effects of changes in temperature, pH, and enzyme concentration on reaction rates of an enzyme catalyzed reaction in a controlled experiment.

Implementation of any Science Project Idea should be undertaken only in appropriate settings and with appropriate parental or other supervision. Enzymes such as catalase are vital to our body, because if toxic substances such hydrogen peroxide were not broken down into harmless substances in our body, then they would poison our cells.

In the third experiment, it was inferred that as the acidity increased in the substrate, the rate of reaction decreased. After testing liver, apple, and potato it was concluded that liver contained the most catalase. The enzyme is not altered by the reaction. Enzymes Objectives Measure the effects of changes in temperature, pH, and enzyme concentration on reaction rates of an enzyme Explain how environmental factors affect the rate of enzyme-catalyzed reactions.

Which one reacted the least? The error within our experiment only altered the specific pH but the overall result of the last test remains true. The enzyme studied in this lab was catalase. Catalase breaks down hydrogen peroxide, which is toxic, into 2 safe substances- water and oxygen, by speeding up a reaction.

This shows that enzymes only work in a certain pH level. This is because the heat degraded the catalase enzyme, making it incapable of processing the hydrogen peroxide.

This enzyme, like many others, aids in the decomposition of one substance into another. Because we were only able to stimulate an environment of a lower pH, we were only able to get 1 direction of slope, showing linear results. The relationship between catalase reaction rate and pH was shown to be parabolic with a peak near neutral.

What would happen to your cells if they made a poisonous chemical? Each of these enzymes is responsible for one particular reaction that occurs in the cell.

The liver will have a large reaction because the majority of liver is proteins and enzymes which break down the Hydrogen Peroxide. You have hundreds of different enzymes in each of your cells.catalase lab report Essay [Teacher] [Course] [Date] Catalase Lab Report An enzyme is something that helps to speed up a chemical reaction.

The enzyme changes. Catalase Enzyme Lab Report Hypothesis If temperature is outside the enzyme's optimal range, then the enzyme activty and amount of oxygen released will decrease because it will not function properly. View Lab Report - Catalase Enzyme Lab Report from BIOL at University of Southern California.

Catalase Enzyme Lab Report Guy Guarino Abstract Enzymes are protein catalyst that speed up the rate of95%(19). The objective of this lab was to develop a protocol to investigate the effect of an environmental variable on the catalytic function of an enzyme.

More specifically, the objective was to perform an experiment in order to test the effect of pH on the function of the enzyme catalase. In this lab, the enzyme catalase was used to break down hydrogen peroxide into less toxic water and oxygen gas.

Using quantitative as well as qualitative observation the concept that enzymes remain after a reaction was confirmed from the first test.

Aug 12,  · In this cool catalase and hydrogen peroxide experiment, kids put a potato in a jar of hydrogen peroxide to see how catalase acts as an enzyme/5().
