Optimal Temperature for Potato Catalase Introduction In this experiment. the optimal temperature of catalase in potatoes will be determined using its substrate hydrogen peroxide solution. The reaction of catalase in hydrogen peroxide solution will change depends on the temperature of the hydrogen peroxide solution. If the reaction time of catalase is related to the temperature of its substrate, when the temperature of hydrogen peroxide reaches to 35-40˚C, the reaction of the catalase will be the fastest
Influence of Temperature on the Activity of Potato Catalase Hypothesis That the higher the temperature the higher the reaction rate of potato catalyse to a point were denaturing occurs in the enzyme and the reaction rate of the potato catalase drops off. Prediction The rate of Catalase activity will be faster at higher temperatures until a point, because at higher temperatures there are more chances of collisions between the enzyme's (Catalase) active site and the substrate (hydrogen
How the Concentration of the Substrate Affects the Reaction in the Catalase Inside Potato Cells Introduction Enzymes are made of proteins and they speed up reactions, this means that they act as catalysts. Hydrogen peroxide is a byproduct of our cell's activities and is very toxic. The enzymes in our bodies break down the hydrogen peroxide at certain temperatures they work best at body temperature, which is approximately 37 degrees. At high temperatures, the cells begin to denature. This
The Effect of Surface Area on the Rate of Reaction Between Catalase from a Potato and Hydrogen Peroxide Aim To find out the relationship between the surface area of a potato chip and the rate of reaction when hydrogen peroxide is put in with it. Variables As I do this experiment the thing I am going to be changing is the surface area of the potato chip, first I will put it in the beaker as a whole (3cm chip) then I will start cutting it into smaller pieces and repeating the experiment
communicate with each other by keeping the life and death of the cell under control. What is the substrate of catalase? A substrate is a substance in which an enzyme reacts. A catalase is an enzyme that destroys harmful substances inside your body. Hydrogen peroxide (H_2 O_2) is produced in the body because of the reactive nature of oxygen. Oxygen atoms that are lost can be used to produce this. Catalase converts H_2 O_2 into the water and oxygen gas, thus, protects the DNA. Describe three safety factors
To investigate the amount of oxygen foam (cm) produced by the enzyme catalase when it breaks down hydrogen peroxide in the animal (liver, milk, honey) and plant cells(potato, purple cabbage) into oxygen and water Motivation: The reason I chose this topic was because I wanted to find out what enzymes are used for, to what extent they are used in our bodies and, how vast are their applications in food industries. Enzymes have been used in research, mainly because of their ability to facilitate reactions

The Rate at Which It is Broken Down by Catalase AIM To find out whether the concentration of Hydrogen Peroxide affects the rate of decomposition of hydrogen peroxide when broken down by catalase. SCIENTIFIC KNOWLEDGE Hydrogen peroxide is a liquid bi-product of many chemical reactions in living things. It is toxic, so has to be broken down by the enzyme catalase which is also found in most living things. E.g. [IMAGE]Hydrogen peroxide catalase water + oxygen 2H2O2 (aq) 2H2 O +
The Effect of pH on the Activity of Catalase Planning Experimental Work Secondary Resources Catalase is a type of enzyme found in different types of foods such as potatoes, apples and livers. It speeds up the disintegration of hydrogen peroxide into water because of the molecule of hydrogen peroxide (H2O2) but it remains unchanged at the end of the reaction. This is a type of reaction where a molecule is broken down into smaller pieces. It is called an anabolic
Measure Rate of Conversion of Hydrogen Peroxide to Water and Oxygen Overview: In this laboratory you will use a chemical titration to measure and then calculate the rate of conversion of hydrogen peroxide (HO) to water and oxygen using the enzyme catalase.

peroxide is a toxic chemical but catalase speeds up the breakdown of hydrogen peroxide into non-toxic substance such as water and oxygen. In this catalase enzyme vs. hydrogen peroxide experiment we ask, what environmental treatment will reduce catalase enzyme activity in a potato? We will discover how a potatoes temperature including hot, cold, and room temperatures will affect the catalase enzyme activity. With this information in mind we hypothesized the potato that
Concentration on Catalase Aims This is an experiment to examine how the concentration of the substrate Hydrogen Peroxide (H2O2) affects the rate of reaction of the enzyme Catalase. Background Information Enzymes such as Catalase are protein molecules, which are found in living cells. They are used to speed up specific reaction within the cell. They are all very specific as each enzyme just performs one particular reaction. Catalase is an enzyme found in food such as potato and liver.
Investigating the Amount of Oxygen Given Off When Catalase Reacts with Hydrogen Peroxide My aim for this investigation is to measure the amount of oxygen given off when we react catalase (enzyme) with hydrogen peroxide (substrate), this means that I aim to investigate the effect of hydrogen on the activity of catalase. Background Information Enzymes such as Catalase are protein molecules that are found in living cells. They are used to speed up specific reaction in the cell. The enzymes
Having a particular enzyme to catalyze each of the chemical reactions that take place in a living cell, total control of metabolism can be sustained by an organism. Catalase is an enzyme found in cellular organelles called peroxisomes. It catalyzes the breakdown of hydrogen peroxide(which is toxic to the cell)to oxygen and water Catalase 2H2O2  O2 + 2H2O Hydrogen Peroxide (enzyme) Oxygen Water (substrate) (Products)
Comparing the Reaction Rates Between Potato and Hydrogen Peroxide Against Liver and Hydrogen Peroxide Through Loss in Mass Background information: Catalase is an enzyme that is found in all cells. This means that it is an intracellular enzyme. And enzyme is a biological catalyst. A catalyst is some thing that speeds up a reaction without being changed itself. Because of this enzymes and catalysts can be used again and again. Enzymes are protein chains that have a primary, secondary and
Biological Effects on Potato Potatoes, like all other vegetables contain the enzyme catalase, which breaks down the toxic waste product of hydrogen peroxide. Potatoes have an unusual response to long exposures of light, where the chemical properties are altered within the cells. This can be seen as the surface changes green in colour. Storage conditions of potatoes are therefore important, to ensure potatoes remain in the original state after cultivation. Within this assessment, the effects
