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
How are manganese dioxide and peroxidase similar?
They both like The Eagles

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 a member of the peroxidase family. Catalase generates water and oxygen while peroxidase generates water and an activated donor molecule. Thus, peroxidase could refer to more than one enzyme.
Are rutabagas high in peroxidase activity?
Rutabagas, like many cruciferous vegetables, do contain peroxidase enzymes, but their peroxidase activity is generally not considered particularly high compared to other vegetables. Peroxidases play a role in various metabolic processes, including defense against oxidative stress. However, specific peroxidase activity can vary based on growing conditions and preparation methods. Overall, while rutabagas have some level of peroxidase activity, they are not typically highlighted for it.
What is the function of magnesium chloride in peroxidase extraction?
Mg2+ is a cofactor of the enzyme peroxidase. In order to keep the enzyme active, this cofactor must be supplied. Magnesium chloride dissociates in solution into magnesium and chloride ions. The cofactor requirement is thus met
