Factors affecting enzyme activity investigating an enzyme-controlled reaction: catalase and hydrogen peroxide concentration use catalase in pureed potato and investigate the effect of changing hydrogen peroxide concentration on rate of production of oxygen. Cells make the enzyme catalase to remove hydrogen peroxide this investigation looks at the rate of oxygen production by the catalase in pureed potato as the concentration of hydrogen peroxide varies the oxygen produced in 30 seconds is collected over water. Investigation: enzymes objectives measure the effects of changes in temperature, ph, and enzyme concentration on reaction rates of an enzyme the name of the enzyme is catalase it speeds up a reaction which breaks down hydrogen peroxide, a toxic chemical, into 2 harmless substances--water and oxygen fresh liver, apple, and potato. Enzymes, like catalase, are proteins that speed up chemical reactions by reducing the amount of energy the reaction needs to take placespecifically, an enzyme reduces the activation energy needed to convert a certain substrate into a particular productfor example, in the catalase reaction in figure 1 above, hydrogen peroxide is the substrate and there are two products, water and oxygen.

The first one determined the dependence of rate of catalase activity in the hydrogen peroxide and without the catalase in the hydrogen peroxide in the first our hypothesis was that the larger the piece of potato the greater the concentration of catalase enzyme and the smaller the piece of potato the lower the concentration of catalase enzyme. A it doesn't seem to me that the effect of copper sulphate on the activity of catalase is that difficult to digest bearing in mind that copper sulphate is a non-active site directed inhibitor, which effects catalase it attaches itself onto a part of catalase (not it's active site), and alters the.
Effect of the concentration of hydrogen peroxide on the rate of reaction of catalase from potato focus question: how will the concentration of the substrate hydrogen peroxide affects the rate of reaction of the enzyme catalase. A grade catalase coursework to investigate the effect of temperature on the rate of reaction of an enzyme “catalase” by measuring the amount of oxygen produced by the reaction i am going to investigate the effect that temperature has because this is an easy variable to change and control using water baths. 4 catalase liver and yeast are used to decompose hydrogen peroxide 401 catalase 402 discussion 403 catalase - preparation all zipped 5 turgor in potato tissue cylinders of potato tissue are immersed in solutions of differing strength and changes in length are measured 501 turgor in potato tissue. I'm doing my biology coursework on potato catalase, and did my experiment today my experiments showed that the optimum ph for potato catalase was ph7 (well, i only tested ph1, ph7 and ph13) but. Biology higher level internal assessment the effect of surface area of potato on the reaction between catalase enzyme and hydrogen peroxide essay about biology enzyme lab – 1504 words following a teacher demonstration of measuring the rate of hydrogen peroxide and catalase enzyme ib biology catalase coursework – extracts from this.
In my coursework i will investigate about enzymes in potatoes reacting with hydrogen peroxide in particular i will investigate the effects of changing the surface area of a potato when added to hydrogen peroxide effect of temperature ( c ͦ) on enzyme catalase activity in potato aim:. The temperature at which the reaction rate is the greatest is referred to as optimum temperature (pang 1997, p70) that is the say, enzyme catalase catalyses the breakdown of hydrogen peroxide the most effectively at this temperature. Hello, i'm doing my gcse additional science coursework and i i'm investigating the rate of reaction of the enzyme catalase and the substrate: hydrogen peroxide the independent variable i chose to investigate was the concentration of enzyme ie changing the concentration of the enzyme we used yeast as a source of enzyme.

Investigation into the effect of ph on the activity of potato tissue catalase aim the aim of my investigation is to see how ph affects the activity of potato tissue catalase, during the decomposition of hydrogen peroxide to produce water and oxygen.
The effect of ph on the rate of enzyme catalysis of catalase objectives: the objective of this lab was to develop a protocol to investigate the effect of an environmental variable on the catalytic function of an enzyme. The fastest known enzyme is called ‘catalase’ and has a turnover number of 6 million it is found in various tissues where it speeds up the decomposition of hydrogen peroxide (h 2 o 2) and converts it into water and oxygen. Coursework writing service essay outline/plan service dissertation services effect of ph level and hydrogen peroxide on catalase print reference this disclaimer: affect the activity of catalase in potato during the decomposition of hydrogen peroxide to produce water and oxygen different variables (independent, dependent and. Easy enzyme experiment: potato catalase catalase enzyme formed the bubbles in the two tubes on the right the tubes contain extracts from beef muscle, kidney, and liver from left to right in a post awhile back we discussed the enzyme catalase and its presence in animal tissues such as liver, kidney, and muscle catalase was and is.
Influence of temperature on the activity of potato catalase - 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. Biology coursework factors affecting the activity of potato catalase on hydrogen peroxide aim: this experiment is based on the simple aim of finding the factors affecting the activity of potato catalase on hydrogen peroxide. Potato catalase description: rate of reaction __ throughout this investigation you will estimate the rate of the reaction (how rapidly the solution bubbles) on a scale of 0-5 (0=no reaction, 1=slow to5= very fast.
The activity of catalase in potato during the decomposition of hydrogen peroxide to produce water and oxygen different tests were carried out, using potato as a source of catalase and reacting it with hydrogen peroxide and ph and the same process was repeated with a banana to compare the rate of reaction.
