What is the effect of the acidity of potato juice on the volume of foam produced when hydrogen peroxide is added to potato juice?
Question: What is the effect of the acidity of potato juice on the volume of foam produced when hydrogen peroxide is added to potato juice? In this investigation, the prediction that if the acidity of potato juice is decreased then the volume of foam was increased was proven incorrect. Catalase is damaged by acid. The lowest foam volume was 24 ml with the highest acidity, pH6, However the highest foam volume was an average of 42 ml with the second lowest acidity level,pH8 The third highest volume was 35 ml with the second highest acidity level pH7, and the second lowest foam volume was 30 ml with the lowest acidity level pH9.
What is the function of amylase in a detergent?
An amylase is an enzyme which helps in the digestion of starch. Enzymes are usually added to biological powders to help in the removal of stains. Starch, being made of very large molecules doesn't dissolve in water. The enzyme helps break it down to sugars, which do dissolve away.
How does boiling a potato effect osmosis?
Boiling the potato destroys the cell membrane which is a partially permeable membrane. Thus osmosis is unable to occur as osmosis occurs through a partially membrane and only diffusion would occur.
Is maltodextrin organic?
Maltodextrin is typically derived from corn, rice, or potato starch. Some manufacturers produce organic maltodextrin made from organic starch sources, which are certified organic according to organic farming regulations. It is best to check the product label or contact the manufacturer to verify if a particular maltodextrin product is organic.
Why the potato becomes turgid in water in osmosis?
When a potato is placed in water, the water concentration outside the potato cells is higher than inside. This creates a concentration gradient that drives water molecules into the potato cells through osmosis, causing the cells to swell and the potato to become turgid. The cell wall of the potato cells helps maintain the shape and prevents them from bursting.
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.
What happens when crushed potato was added to hydrogen peroxide?
When crushed potato is added to hydrogen peroxide, the enzyme catalase in the potato catalyzes the decomposition of hydrogen peroxide into water and oxygen gas. This reaction produces bubbling or foaming as the oxygen gas is released.
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 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.
Why does liver break down H2O2 faster than potato?
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.
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.
Why do the boiled and unboiled potato extracts differ in their action on hydrogen peroxide?
hope this is correct. it is because the boiled potato has a denatured enzyme resulting it not to have a reaction with h2o2 while the unboiled potato has no denatured enzyme that's why it reacts.
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).
How does a crush potato differ from a whole potato when hydrogen peroxide is added to each separately?
it tasts funny =)
How does Hydrogen peroxide decomposes much faster in the presence of enzyme catalysts?
Enzymes act as catalysts by lowering the activation energy required for a chemical reaction to occur. In the case of hydrogen peroxide decomposition, enzymes such as catalase can significantly speed up the breakdown of hydrogen peroxide into water and oxygen. The enzyme provides an alternative reaction pathway that allows the decomposition to happen more rapidly.
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 is potato enzymes?
Potato enzymes are proteins found in potatoes that play a role in various biochemical processes such as metabolism and growth. Some common potato enzymes include amylase, which breaks down starch into sugars, and catalase, which helps break down hydrogen peroxide into water and oxygen.
