Enzyme Catalase Essay

Purpose: To find out how modifying the variables of concentration, temperature, and pH effects enzyme activity. Hypothesis and Rationale x3 (Concentration, Temperature, pH): If the concentration of the catalase is decreased, then enzyme activity will decrease as well, because there is less catalase, which is what sparks the chemical reaction. If the temperature of the catalase is increased, then enzyme activity will rapidly increase as well, because an increase in temperature increases the kinetic

rate of reaction between Catalase and the hydrogen peroxide (H2O2) can vary depending on many factors including the enzyme concentration in a solution. In this investigation, the rate of reaction will be measured by the change in temperature of the liquefied spinach (catalase) over a period of 30 seconds, once the hydrogen peroxide (H2O2) has been added into the solution. It is expected that the change in temperature will initially increase as the concentration of the Catalase increases in the hydrogen

pH level and temperature affects enzyme activity. Enzymes are proteins in living things that speeds up chemical reactions. We used a specific enzyme, catalase which breaks down hydrogen peroxide into water and oxygen. The oxygen released from the chemical reactions creates gas bubbles, also known as foam. By measuring the foam, we are able to determine how active the enzyme is. If there is a big amount of foam produced in the test tubes, there is a lot of enzyme activity. If there is little to no

temperature has on the Catalase enzyme’s ability to catalyze hydrogen peroxide production and turn it into oxygen as well and to determine at what point denaturation of the enzyme starts to occur. Catalase’s ability to catalyze hydrogen peroxide was tested at 4 different temperatures: 0, 23, 37 and 55° Celsius. Enzymes are the catalyst in many cellular reactions. They speed up the reaction in other molecules by making the activation energy barrier they have to overcome less. Each enzyme is a specific protein

the working of a biological catalyst: catalase The topic being investigated was the working of a biological catalyst. An enzyme is a protein that acts as a biological catalyst of chemical reactions and is capable of speeding chemical reactions. The shape of each enzyme is very precise and this gives the enzyme the ability to catalyze one specific reaction. Enzymes have a three dimensional shape, which is essential to the way it functions. In every enzyme there is a region called active site where

to what extent, altering the hydrogen peroxide concentration, temperature, synthetic catalase and natural peroxidase; sourced from plants, would affect the overall rate of reaction of the enzyme catalase. This was represented by a significant increase in oxygen gas pressure over a specific period of time. It was hypothesised an increase in temperature would have the most significant effect over the optimal catalase activity and rate of reaction of 50°C. It is clearly evident that the concept of altering

Taylor Hill Lab 6: Enzymes Purpose: The purpose of this lab is to test for enzyme activity, look at enzyme specificity, and how temperature affects enzyme activity. Hypothesis: I believe that the room temperature activity will produce the most activity. Materials: 3% hydrogen peroxide, a household blender, potatoes (3 medium size potatoes, that are peeled and quartered), tap water, 8 test tubes, 8 transfer pipets, sugar packets, salt, a small saucepan, a refrigerator with a freezer, stove

Amenah Ali Ms.Corbett IB Biology HL I Period 5 December 13, 2017 Enzyme Design Lab Research Question: At what temperature does an enzyme react at its optimum rate? Background Information: Hydrogen Peroxide is a by product of many biological and chemical functions of organism. Although it is toxic, it still remains in our cells. To counter the hydrogen peroxide we produce something called a catalase. This means that with a catalase, it can cause the chemical reaction to speed up the reaction of

to study the effect of varying temperatures on the enzyme catalase by measuring the oxygen production as it breaks down hydrogen peroxide. Introduction Enzymes are used in our daily lives in many ways. From industry to agriculture, enzymes play a necessary role in everything from bread to laundry soap. In medicine, enzymes can speed up, slow down, or block cellular reactions in the body. Enzyme reactions can be measured as a diagnostic tool. Enzymes and their effects are important to study because

was undertaken to demonstrate and observe the effect of enzymes acting as a catalyst in many reactions within cells, focusing specifically on the enzyme that decomposes hydrogen peroxide, catalase. This enzyme is extremely prevalent in vertebrate liver cells. Hydrogen peroxide is a regular product in many cellular reactions, but the substance can be toxic, and therefore needs to be broken down to conserve the cells. This is where catalase is effective in speeding up the reaction for hydrogen peroxide
