To Investigate The Effect Of Temperature On The Enzyme Catalase Essay
While the free essays can give you inspiration for writing, they cannot be used 'as is' because they will not meet your assignment's requirements. If you are in a time crunch, then you need a custom written term paper on your subject (to investigate the effect of temperature on the enzyme catalase)
Here you can hire an independent writer/researcher to custom write you an authentic essay to your specifications that will pass any plagiarism test (e.g. Turnitin). Waste no more time!
Hypothesis ;Hydrogen peroxide will breakdown to oxygen and water in the presence of Catalase. The reaction will increase with increasing enzyme concentration when molecules of hydrogen peroxide are ...
To investigate the effect of temperature on the enzyme Catalase.
To investigate the effect of temperature on the enzyme Catalase.
††††††††† The aim of this experiment is to determine the effects of varying temperatures on enzyme (Catalase). We will conclude the experiment by establishing the enzymes optimum temperature (the temperature at which it works best at). We will also carry out some simple experiments using the substrate Hydrogen Peroxide.

††††††††† The aim of this experiment is to determine the effect of varying temperature of enzyme Catalase.
.Inverted measuring cylinder
Using the equipment safely
††††††††† It is important that we use the apparatus carefully, as safety will be an issue through out the whole experiment. We will wear goggles and an apron, to protect our eyes and clothes. As we are
Enzyme Action: Testing Catalase Activity Introduction: Enzymes are proteins that serve as catalysts and accelerate chemical reactions in living organisms. Enzymes accomplish this by lowering the energy of activation of ...
††††††††† Catalase is an enzyme found in all living cells. It makes Hydrogen Peroxide decompose into water and oxygen. We will measure the amount of Oxygen
I am going to investigate whether pH effects the rate at which catalase decomposes hydrogen peroxide. ‚ÄėCatalase is a biological enzyme (enzymes work best at a certain pH) found in ...
††††††††† To make the test fair, the following parameters must remain constant during the experiment. These parameters are water, Hydrogen Peroxide, Catalase, room temperature and the duration of the reactions. If the reaction reacts too quickly we may
Hypothesis ‚Äď Hydrogen peroxide will breakdown to oxygen and water in the presence of Catalase.¬† The reaction will increase with increasing enzyme concentration when molecules of hydrogen peroxide are freely ...
Dependant Variable: rate of breakdown of Hydrogen Peroxide, time
Independent Variable: temperature of solution.
Control Variable: Volume of Hydrogen Peroxide, volume of Catalase solution, concentration of Hydrogen Peroxide, concentration of Catalase.
††††††††† I predict that the breakdown† of Hydrogen Peroxide will be quicker when the temperature is increased until it exceeds 40°C. I predict that the enzymes optimum temperature is 23°C (room temperature)
INTRODUCTION The enzyme catalase speeds up the decomposition of Hydrogen Peroxide into water and oxygen as shown here, 2H2O2-------------------*2H2O+O2. It is one of the fastest known enzymes and its ...

††††††††† At low temperatures particles of reacting substances do not have much energy. However, when the substances are heated, the particles take in energy. This causes them to move faster and collide more often. The collisions have more energy, so
AIM Effect of temperature of the action of the Enzyme Catalase. PLANNING Background Knowledge An enzyme is a biological catalyst, it alter the rate of reaction without being changed itself. ...
††††††††† The more successful the collisions are the faster the reaction.
††††††††† The same can be said for reactions controlled by enzymes, but because enzymes are proteins if the temperature exceeds 50°C the enzyme will be denatured and will no longer work. For this reason few cells can tolerate temperatures higher than approximately 45°C.
††††††††† Enzymes are specific in the reactions they catalyse, much more so than inorganic Catalysts.
Aim: To investigate the effect of temperature on the enzyme catalase. Prediction: Using my existing scientific knowledge, I predict that as I raise the temperature to 30, 35, and 40, ...
I have to plan and carry out an experiment to investigate the way in which concentration of a substrate affects the rate of an enzyme-catalysed reaction. I will need ...
††††††††† So the higher the temperature of the Hydrogen Peroxide
For this investigation I have been asked to investigate (by experimentation) the effect of substrate concentrations on the rate of the decomposition of hydrogen peroxide when catalyzed by the enzyme ...
We will be measuring three main factors:-
.Temperature-the optimum temperature of the enzyme.
.Oxygen-the amount released from the Hydrogen peroxide.
.Time- the duration of the reaction.
††††††††† The room temperature may
IntroductionIn this experiment I will attempt to investigate the factors that effect the rate of reaction of the enzyme catalase. ¬†¬†¬†¬†¬† Catalyse is an enzyme found in food ...
††††††††† To make it fair we will allow the reactions to have the same amount of time to occur. We will change the TEMPERATURE of the Hydrogen Peroxide.
This is what our results table will look likeÖ
AMOUNT OF O₂ ;RELEASED (ml)
0°c (crushed ice)
23°c (room temp)
††††††††† As you can see from the results table we will be taking six measurements of the temperature ranging from (0°c to 100 °c). I predict that the enzyme will be totally denatured at 100°c and will no longer be active. We also predict that the optimum temperature of this enzyme is 23°c (room
