Outline the effect of temperature on the activity of urease enzyme. [2 marks] State one factor that would need to be controlled in this experiment. [1 mark] 2. The enzyme amylase was extracted from the digestive system of horses and added to whole cereal grains (seeds) in test tubes at ...
3 Catalase is an enzyme that breaks down hydrogen peroxide inside cells. Red blood cells contain catalase.Some dogs have an inherited condition in which catalase is not produced. This condition is known as acatalasi a and it is caused by a mutation in the gene for catalase.(a) Define the...
Students will be observing normal catalase reaction, the effect of temperature on enzyme activity, and the effect of pH on enzyme activity in this experiment. The enzymes will all around perform better when exposed in room temperature than when it is exposed to hot and cold temperatures. This ...
The oxygen electrode/C60-catalase detection system exhibited linear responses to the concentration of hydrogen peroxide and amount of immobilized C60-catalase enzyme that was used. The effects of pH and temperature on the activity of the immobilized C60-catalase enzyme were also investigated. Optimum ...
Why does the enzyme catalase bubble when hydrogen peroxide is added (yeast-hydrogen peroxide experiment)? What is an enzyme? Why is it important? Why are bacteria such a useful source of enzymes? Explain how the enzyme catalase is affected by temperature and PH, including "denature." ...
The substrate in our experiment was hydrogen peroxide and the enzyme itself was catalase which was extracted from potatoes. The products of this substrate-enzyme interaction were H20 and O2. The first test that was conducted involved the concentration of enzymes in potato cells. The independent ...
Catalase Enzyme Lab Report The data from the experiment demonstrates that the catalase enzyme breaks down the hydrogen peroxide due to its harmful toxicity to the liver. In section A‚ the effect surface area has on the enzyme was tested. The results have proven that as the surface area in...
catalase and hydrogen peroxide. This experiment was performed by measuring and comparing the amount of oxygen bubbles produced and the absorbance of the catalase and hydrogen peroxide solution over time at roomtemperature‚ 2°C‚ 50°C‚ and 60°C. The overall result of this ...
(enzyme competing with HRP for hydrogen peroxide). (d) Channeling diagram showing the region where the enzyme proximity can at least double the reaction velocity. The diagram is drawn in the plane of the concentration of enzyme complexes and the concentration of catalase. We have assumed that [...
aCatalase is an antioxidant enzyme that, like superoxide dismutase (SOD) and glutathione peroxidase, is produced naturally within the body. It helps the body to convert hydrogen peroxide into water and oxygen, thus preventing the formation of carbon dioxide bubbles in the blood. Catalase also uses...
