Potato catalase coursework
The reaction is less reactive in boiled liver compared to manganese dioxide the difference is caused by the sensitivity of catalyst towards heat liver contains enzyme catalase which is very sensitive to heat while manganese dioxide is an inorganic catalyst which is not sensitive to heat. I've been reading a lot of these posts and i think one big thing to consider is that using a liver cell or potato cell or yeast cell (which is what i regrettably did for my coursework) is actually very different from using pure catalase since cells can die or the copper can't get past the cell membrane or the copper has a higher affinity for . 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. Potato provides a suitable source of catalase and the ph is varied in this experiment using citric acid-sodium phosphate buffer solutions at ph values of 44, 52, 65 and 75 catalase is an enzyme, a biological (organic) catalyst.
