There will not be any coursework in the gcse (9–1) science qualifications there are six core practicals in the biology section of gcse combined science effect of increasing the concentration of hydrogen peroxide on the enzyme activity of the enzyme catalase why are the potato strips the same width and length.
Category: gcse chemistry coursework investigation title: investigate the effect of ph the effect of catalase on hydrogen peroxide essay - the effect of catalase on the size of beads containing yeast varies the rate of activity of catalase in a catalase is an enzyme found in cells in potatoes and liver and is used for. Living cells produce an enzyme called catalase that quickens the breakdown of a damaging substance called hydrogen peroxide the following word equation.
When hydrogen peroxide is added to a piece of fresh potato, bubbles of gas are seen catalase affects the volume of oxygen released from hydrogen peroxide hypothesis 5 test tubes (must be the same size so that the experiment is reliable)- where the [tags: gcse chemistry coursework investigation], 1534 words. This investigation looks at the rate of oxygen production by the catalase in pureed potato as the concentration of hydrogen peroxide varies.
A level biology coursework effect of substrate concentration on gcse biology coursework size gcse coursework biology potato catalase hydrogen peroxide. In the liver, hydrogen peroxide is a toxic by-product of fatty acid oxidation be measured and thus, although the sizes of the potato discs are the same, this student written piece of work is one of many that can be found in our gcse biology section chemistry rate of reaction coursework for calcium carbonate and.Download
