Peroxidase in plants helps in the breakdown of hydrogen peroxide, a harmful byproduct of metabolism, into water and oxygen, which are less damaging to plant cells. It also plays a role in the defense against pathogens by producing toxic compounds that are harmful to them. Additionally, peroxidase is involved in the lignification process, which strengthens cell walls in plants.

Where is peroxidase found?
Peroxidase is found in various organisms such as plants, animals, and microorganisms. In humans, peroxidase is present in tissues like the thyroid gland and the intestines. In plants, peroxidase is found in cells, particularly in the roots, stems, and leaves.
Is potato peroxidase destroyed by boiling?
Yes, boiling can denature peroxidase enzymes and potentially destroy their activity. High temperatures can break the hydrogen bonds holding the protein structure together, leading to a loss of enzyme function.
What happens to peroxidase when the pH is on either side of the optimum?
When the pH is above or below the optimum range for peroxidase, the enzyme's activity decreases. This is because the active site of the enzyme is influenced by the pH, affecting its ability to bind to the substrate. Consequently, the enzyme's catalytic function is compromised, leading to reduced efficiency in catalyzing the reaction.
What is the function of surcose in plants?
Sucrose's function in plants are that they are a major component in the structure tough walls of plants :) Hope this helped

What is peroxidase?
It is an enzyme that breaks down Hydrogen Peroxide.
What fruits are rich in peroxidase?
What fruits or vegetables are rich in peroxidase?
What is mushroom peroxidase?
A peroxidase is an enzyme that, as the name suggests, breaks down peroxides."Mushroom peroxidase" would be such an enzyme derived from mushrooms.
What effect does boiling the material have on peroxidase activity?
Boiling typically denatures peroxidase enzymes, leading to a loss of activity. The high temperatures disrupt the enzyme's structure, preventing it from functioning properly as a catalyst for peroxidase reactions.
Is potato peroxidase destroyed by boiling?
Yes, boiling can denature peroxidase enzymes and potentially destroy their activity. High temperatures can break the hydrogen bonds holding the protein structure together, leading to a loss of enzyme function.
How does the presence of HCl affect activity of peroxidase?
HCl can denature peroxidase, causing a decrease in its activity. The acidic pH from HCl disrupts the enzyme's structure, leading to a loss of function. Additionally, HCl can alter the chemical environment necessary for the enzyme to carry out its catalytic reaction.
Is cabbage a high peroxidase vegetable?
no

What is the basic difference between catalase and peroxidase?
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.
What is the function of magnesium chloride in peroxidase extraction?
Magnesium chloride is often used in peroxidase extraction to help stabilize the enzyme and prevent its denaturation during the extraction process. It also aids in maintaining the enzyme's activity and integrity during storage and subsequent use in various assays.
What is the main function in starch in plants?
The main function of starch in plants is to store energy.
