After reviewing the basics of enzymes and catalysis, we take a dive into the wonderful
world of catalase. Beginning with establishing a base line of just how much hydrogen
peroxide there is in 5.0mL of the reacted solution; to figuring out exactly how much
actually reacted after 300...
Abstract: Catalysis is an enzyme that decomposes hydrogen peroxide into oxygen and water. In this lab we will conduct a series of experiments to determine the affects of; pH, temperature, and concentration change on such catalysis. After completing the experiments we determined t...

Problem: Measuring the effects of Catalase enzymes on hydrogen peroxide decomposition. Measuring the rate of the reaction when hydrogen peroxide and Catalase are mixed at...
The purpose of this lab was to observe and understand the effects of changes in temperature, pH, enzyme concentration, and substrate concentration on the reaction rate of an enzyme-catalyzed reaction. Another purpose of the lab was to explain how environmental factors affect the rate of...
This lab allows us to observe the conversion of hydrogen peroxide (H2O2) into water and oxygen gas. An enzyme known as catalase facilitates this decomposition reaction. The catalase enzyme acts as catalysis, helping lower the energy needed to activate the reaction while the enzyme itself...

Catalase is a common enzyme found in nearly all living organisms that is frequently used by cells to rapidly catalyze the decomposition of hydrogen peroxide into less reacti...
Investigation on the effects of Temperature, pH levels, and Enzyme Concentration
on the reaction rate of the Decomposition of Hydrogen Peroxide by Catalase
The purpose of this investigation is to figure out how temperature, pH, and enzyme concentration affect the reaction rate of an enzyme. It...

Peroxidase is an enzyme found in potatoes that catalyzes the breakdown of hydrogen peroxide, H2O2, into O2 gas and water. We examined the different pH environm...
Lab 7 Enzyme Catalysis Lab Activity
1. The function of enzymes in a living system is to speed up chemical reactions.
2. The place in the human body where it would be beneficial to have enzymes that wrok in a very acidic environment would be the stomach, because it contains an enzyme call...
Rate of Reaction of Enzyme-Catalase with different temperature of hydrogen peroxide
Enzymes are proteins produced by the body that help certain biochemical reactions take place in the body. Chemical reactions require a certain amounts of energy in...
AP Laboratory : Enzyme Catalysis
Purpose - The purpose of this lab is to use a chemical titration to measure and them calculate the rate of conversion of hydrogen peroxide (H2O2) to water and oxygen gas using the enzyme catalase.
Hypothesis - The rate of enzymatically-catalyzed reactions can...

1] Are enzymes reusable?
Yes, enzymes are reusable.
2] Which of the following do you think contain catalase? [Manganese dioxide, chicken meat, apple, carrot, potato, or chicken liver]
I think that the manganese dioxide, apple, and carrot contain the c...

Enzyme Catalyst Lab - Formal Report – August 8, 2007
This investigation examined what would happen to the rate of an enzyme-catalyzed reaction if the concentration of substrate changed. We hypothesized that if the concentratio...

Enzymes are catalytic proteins, meaning they speed up chemical reactions without being
used up or altered permanently in the process. Although various enzymes use different methods,
all accomplish catalysis by lowering the activation energy for the reaction, thus allowing it to
occur more easily....
AP Lab 2: enzyme catalysis report
To observe the conversion of hydrogen peroxide to water and oxygen gas by the enzyme catalase, measure the amount of oxygen generated, and calculate the rate of the enzyme-catalyzed reaction.
If the time of enzyme reacts with the solution l...
The plot of enzyme activity Vs. pH is often "bell shaped" since two different amino acid groups of the enzyme are being titrated to different states of ionization at the different pH values. This means that only one of the two possible ionization states of the amino acid side chain is effective in e...
