Potatos are more planted than the other one.
it depends on the fruit and the vegetable
Fresh liver contains the enzyme catalase, which breaks down hydrogen peroxide into oxygen and water, leading to bubbling. Potato cubes do not contain catalase and therefore do not produce bubbles when exposed to hydrogen peroxide. This difference in reaction is due to the presence or absence of catalase enzyme in the tissues.
The liver contains higher levels of catalase enzyme, which breaks down hydrogen peroxide (H2O2) into water and oxygen. Potatoes also contain catalase, but in lower levels compared to the liver. This difference in enzyme concentration causes the liver to break down H2O2 faster than potatoes.
The longer it takes for the bubbles to stop forming, the more catalase there is present, assuming that there is enough peroxide (H2O2) to keep the catalase going.
Animal cells typically have higher levels of catalase compared to plant cells, as catalase plays a crucial role in breaking down hydrogen peroxide produced during cellular metabolism in animal cells. Plant cells also have catalase enzymes but at lower levels since they have additional antioxidant enzymes to handle reactive oxygen species.
you need to test both the experiment-organism and an organism which you already know is catalase-positive, in the same environment in order to compare the results and determine if your experiment-organism is catalase-positive. - See more at: http://www.chacha.com/question/why-is-it-advisable-to-perform-a-catalase-test-on-a-known-catalase%26%2345%3Bpositive-organism-along-with-the-organism-you-are-testing#sthash.oChX8ZqW.dpuf
Catalase is an enzyme that specifically breaks down hydrogen peroxide into water and oxygen, while peroxidase is a group of enzymes that catalyze the oxidation of a substrate by hydrogen peroxide. Catalase is highly specific for hydrogen peroxide, while peroxidase enzymes are more versatile in the types of reactions they can catalyze using hydrogen peroxide as a substrate.
The amount of catalase in foods can vary due to factors such as the type of food, how it's processed, and the presence of natural enzymes. Foods like liver, kidney, and potato have higher levels of catalase compared to other foods. Catalase levels may also differ depending on how fresh the food is and the specific growing or storage conditions.
When liver tissue is crushed and exposed to hydrogen peroxide, the enzyme catalase in the liver reacts with the peroxide, breaking it down into water and oxygen. This reaction produces bubbles of oxygen gas and can be used to demonstrate the presence of catalase in living tissues.
A more specific calculation can be done if the particular brand and style of soup is known. In general, one cup of canned vegetable beef soup prepared with one can of water contains 76 calories.
the liver has more enzymes that the potato (a starch) does.
