Temperature Affecting Enzyme Activity Introduction The basic properties of life revolve around chemical reactions. Without the presence of enzymes some of life’s processes would not come so easily. Enzymes are basically proteins‚ which have specific shapes for different substrates. Enzymes change the rate in chemical reactions. It does this without having to change its own shape‚ which makes enzymes different from other proteins. A common enzyme that we have is catalase‚ which breaks down

Vaishnavi Kothapalli Mrs. Manning Honors Biology 30 November 2012 TITLE: The Reaction Rate of Catalase in Various Concentrations of Hydrogen Peroxide QUESTION: How long does the catalase take to float to the top of a cup filled with different amounts of hydrogen peroxide concentration? PREDICTION: A prediction that can be made for this experiment is that the higher the concentration‚ the faster time it takes the catalase to react with the solution. As the concentration increases from

for the effects of temperature on the enzyme activity was that the reaction’s rate would increase as the temperature increased‚ until they go over the optimum temperature where the enzymes denature and the reaction’s rate quickly drops to zero. At 5 degree C the rate is 0.00059mole PNP/min. This then increases to 0.01031mmoles PNP/min at a temperature of 50 degree C. The rate then drops drastically to -0.00215moles PNP/min. This point is where the enzymes have been denatured and have no activity

Enzymes are catalytic proteins which speed up the rate of reactions. Every enzyme has a specific function – meaning‚ they can only bind to certain substrates. Because these enzymes are proteins‚ they can be denatured. Enzymes can be denatured by many factors‚ such as pH and temperature. This lab was divided into three parts which examined the effects of pH‚ enzyme concentration and temperature on the rate of which enzymes catalyze. The pH is an index of hydrogen ions. In acidic conditions‚ where

In order to gain more information for the hypothesis‚ one must know how to test for said macromolecule. Each of the above stated molecules has their own individual solution that will in turn identify which molecule is present. The corresponding test are as followed; Sudan IV is used for testing for lipids‚ if in fact a

Write a balanced chemical equation with state symbols for the reaction catalyzed by peroxidase. 2H2O2 2H2O + O2 (4H1 4O) (4H + 2O + 2O) 2. What is the substrate(s) of this reaction? What is the catalyst? Substrate = H2O2 hydrogen peroxide Catalyst = peroxide 3. At what approximate temperature do enzymes normally operate in the body of a warm-blooded animal? Would your answer change if the enzyme came from a plant or yeast? Enzymes normally

temperature has on the rate of enzyme activity. The way we figured this out was by taking four different temperatures and testing the difference absorbance levels they produced every 20 seconds for about 2 minutes straight using a spectrophotometer. The important part of this experiment was the temperature the enzyme concentration was made at. What we got from the experiment was at lower temperature we got very low numbers for the absorbance‚ which gave us a lower rate for the enzyme reaction to complete‚

purpose of this experiment is to study how enzyme activity is affected by environmental conditions. Researchers tested the level of potato extract enzyme activity with 1-11 pH‚ varying temperature‚ catechol solution‚ hydroquinone solution‚ and different measurements of catechol. In Figure 1A and 1B‚ pH levels were tested with potato extract to see how pH would affect the amount of Benzoquinone is formed in the potato. Although it was hypothesized that enzymes would form Benzoquinone better in acidic
