What happen when a raw potato is mixed with hydrogen peroxide?
When a raw potato is mixed with hydrogen peroxide, the enzyme catalase in the potato helps break down the hydrogen peroxide into water and oxygen gas. This reaction produces bubbles of oxygen gas as a result of the decomposition of hydrogen peroxide.
Why does bubbling occur when hydrogen peroxide is added to the catalase potato?
The hydrogen peroxide, H2O2 , is being decomposed into water and oxygen gas (the bubbles).
What effect does hydrogen peroxide have on potato and does it differ for each type of potato?
Hydrogen peroxide can cause an oxidative reaction on potatoes, which can change their texture, taste, and color. The effect may vary slightly depending on the type of potato due to differences in starch content and enzyme composition, but in general, most potatoes will exhibit a similar reaction to hydrogen peroxide.
How do you reduce hydrogen peroxide to water in homely method?
You can decompose hydrogen peroxide into water by adding a few pieces of uncooked diced potato or liver to it. Both potatoes and liver contain enzymes that will break down hydrogen peroxide.
What were the differences between the reactions of fresh liver and potato cubes in hydrogen peroxide?
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.

What is the enzyme in potato which breaks down hydrogen peroxide?
The enzyme in potatoes that breaks down hydrogen peroxide is called catalase. Catalase helps to convert hydrogen peroxide into water and oxygen, which prevents oxidative damage in the potato cells.

The hydrogen peroxide, H2O2 , is being decomposed into water and oxygen gas (the bubbles).

How does a crush potato differ from a whole potato when hydrogen peroxide is added to each separately?
it tasts funny =)

If you add a piece of hydrogen peroxide tiny gas bubbles will form. However if you crush the piece of potato first more gas bubbles will form. Explain these observations?
The crushed piece has a greater surface area, and so the reaction takes place easier and faster.
Do potatoes have catalase?
Yes they do. Catalase in general seems to protect organisms, including potato cells, from the effects of hydrogen peroxide. In plants, catalase is primarily located in peroxisomes, cell organelles which are like lysosomes, but break down simpler molecules. Catalase is involved in decomposition of hydrogen peroxide generated during cellular processes such as photorespiration and oxidation of fatty acids. Hope this helps :)
Why do the boiled and unboiled potato extracts differ in their action on hydrogen peroxide?
Boiling potato extracts can denature enzymes present in the extract, making them less effective in breaking down hydrogen peroxide compared to unboiled extracts where the enzymes are still active. Enzymes are proteins that catalyze chemical reactions, and denaturation disrupts their shape and function.
Do potato cells have catalase?
Yes, potato cells do contain the enzyme catalase. Catalase is an antioxidant enzyme present in many living organisms, including plants like potatoes, where it helps break down hydrogen peroxide into water and oxygen.
What is the effect of the acidity of potato juice on the volume of foam produced when hydrogen peroxide is added to potato juice?
The acidity of potato juice can affect the volume of foam produced when hydrogen peroxide is added by influencing the speed of the reaction between hydrogen peroxide and the enzyme catalase in the potato juice. Higher acidity may denature or inhibit catalase, leading to a decrease in the volume of foam produced, while lower acidity may enhance the catalytic activity of catalase, resulting in more foam.
