Investigating an enzyme catalyzed reaction

Apparatus and Chemicals For each group of students: Ask students to explain how values over 22 cm3 could happen.

Set out in brown bottles Note 1. When you have squeezed out most of the remaining liquid, pour the liquid from this new jar into the jar with the original filtered catalase solution. Write the time in seconds in the table in your lab notebook.

Cut a coffee filter into small squares. If collecting the gas over water is complicated, and you have access to a cm3 gas syringe, you could collect the gas in that instead. Enzymes are proteins that speed up the rate of reactions that would otherwise happen more slowly.

Yes, I Did This Project! Take a clean beaker or jar, put a new coffee filter in place, and re-filter the catalase solution into the new container.

Use the catalase solution as soon as you make it. The filter square should sink, and then rise to the surface of the hydrogen peroxide again, as shown in Figure 5 below. The activity of the catalase enzyme in the solution decreases over time.

Enzyme-Catalyzed Reactions— What Affects Their Rates?

The most important thing is to be consistent with each test that you run. The coffee filter ripped while I was filtering the catalase solution and unfiltered solid material fell into the jar. Rearrange the ice so that it completely surrounds the catalase solution container but make sure no ice falls into the solutionas shown in Figure 3 below.

In this lab, you will study the catalase found in liver cells.

Investigating an enzyme-controlled reaction: catalase and hydrogen peroxide concentration

Make sure the hydrogen peroxide is at room temperature for at least an hour before using it for this project. It is best to make your catalase solution right before you plan to use it.

The filter paper is not rising. Record this in the table in your lab notebook, along with the exact temperature of the water.More about An Investigation on the Rate of Reaction of the Enzyme Catalase on the Substrate Hydrogen Peroxide.

Lab Report on Measuring the Rate of Conversion of Hydrogen Peroxide using Enzyme Catalysis. Tyrosinase catalyses two specific reactions: first, the hydroxylation of monophenols to o-diphenols and the subsequent oxidation of o-diphenols to o-quinones.

- Investigating Enzyme Activity Aim: To investigate how the concentration of hydrogen peroxide effects the rate of reaction of an enzyme (catalase) Variables: These factors could effect the rate of reaction on an enzyme: · pH · Concentration · Temperature · Surface Area pH - Enzymes function at different pH values.

Cells make the enzyme catalase to remove hydrogen peroxide. Investigating an enzyme-controlled reaction: catalase and hydrogen peroxide concentration | Nuffield Foundation Class practical or demonstration Hydrogen peroxide (H2O2) is a by-product of respiration and is made in all living cells.

Running head: LAB 5: INVESTIGATING AN ENZYME-CATALYZED REACTION Lab 5: Investigating an Enzyme-Catalyzed Reaction September 24, Principles of Biology Mrs. Annemarie Duncan Abstract: (Burmania) This experiment was performed in order to examine ways in which a potato catalase enzyme reacts to various assays.
