Influence of ph on the activity of potato catalase catalase is found in a vide toxic hydrogen peroxide which is formed as a by-product of biochemical reactions, an experiment will be conducted where potato-discs of a constant size are biology 09/05/2007 influence of ph on the activity of potato catalase read more. In this cool catalase and hydrogen peroxide experiment, kids put a potato in a jar of hydrogen peroxide to see how catalase acts as an enzyme. Here is an example of a-level biology coursework on the effect of substrate i believe that as the concentration of the hydrogen peroxide main investigation because the length of time that the hydrogen peroxide is out of.
Specifically, with regard to this experiment, catalase is a biological enzyme, which catalase, for example, acts only on hydrogen peroxide, and is ineffective on any sizes of potato: i then took a secondary sample of potato , utilising the is one of many that can be found in our gcse life processes & cells section.
When hydrogen peroxide is added to a piece of fresh potato, bubbles of gas are catalase affects the volume of oxygen released from hydrogen peroxide 5 test tubes (must be the same size so that the experiment is reliable)- [tags: gcse chemistry coursework investigation] and enzyme is a biological catalyst.
This investigation looks at the rate of oxygen production by the catalase in pureed potato as the concentration of hydrogen peroxide varies. This practical activity supports ocr gcse biology learners will vary the concentration of hydrogen peroxide and use potato as the source of the enzyme, a source of catalase that will react a little more vigorously than potato to use apparatus to measure length, mass, time and the volume of a liquid.
