the reaction will stop because the introduced substance that binds to the reaction site will change the shape of the reaction site so that the original substrate will no longer fit

How does sulfuric acid stop the catalase reaction?

Sulfuric acid denatures the protein structure of catalase enzyme by disrupting its tertiary and quaternary structures through hydrogen bond disruption and charge interactions. This denaturation process alters the catalytic active site, leading to a loss of enzyme function and inhibition of catalase reaction.


What are some examples of chemical activity?

when a metal can replace another metal in a chemical reaction - it is a chemically active metal


What organic substance is catalase made of?

Catalase is an enzyme made of protein. It contains a heme group with an iron atom at its active site, which is crucial for its catalytic function in breaking down hydrogen peroxide into water and oxygen.


What is the point of boiling a catalase?

Boiling catalase denatures the enzyme, meaning it disrupts its structure and renders it inactive. This can be useful in experiments to study the effects of temperature on enzyme activity or to deactivate the enzyme before further analysis.


Why doesnt molecules of other chemicals dont fit into the active site of catalase?

Catalase has a specific shape in its active site that is complementary to the hydrogen peroxide molecule. Other chemicals may have different shapes that do not fit properly into the catalase active site, preventing them from being efficiently broken down. Additionally, catalase has a specific mechanism for reacting with hydrogen peroxide, so other chemicals may not be recognized or processed in the same way.


What does catalase do to hydrogen peroxide?

Because the shape of the active site on catalase only permits it to break down hydrogen peroxide. This is the case for many enzymes such as catalase, although some enzymes can break down more than one substrate.


What is catalase test?

Catalse Test Catalase (also known as peroxidase) is an enzyme that catalyses the breakdown of hydrogen peroxide to oxygen and water. Most higher organisms produce catalase, but in bacteriology this test is usually used to differentiate staphylococci (Catalase positive) from streptococci (Catalase negative). Chemical equation for the breakdown of hydrogen peroxide:2H2O2 → 2H2O + O2 In this test a drop of hydrogen peroxide is emulsified with the bacterial growth, if the organism is catalase positive active bubbling is seen (formation of oxygen) In catalase negative reactions no active bubbling is seen


What inhibits catalase?

Catalase can be inhibited by certain chemicals like cyanide, azide, and heavy metals, as well as by extreme pH levels. Competitive inhibitors that bind to the active site of catalase can also hinder its function.


What is the part of the enzyme into which the substance fits?

Where the substrate and the enzyme fit is called the active site. There are substance that can inhibit this fit.Natural poisons are often enzyme inhibitors that have evolved to defend a plant or animal against predators. These natural toxins include some of the most poisonous compounds known.


What is a substance that slows down or stops a chemical reaction?

An inhibitor is a substance that slows down or stops a chemical reaction by interfering with the reaction process. This can be achieved by binding to the reactants, blocking active sites on enzymes, or changing the pH of the environment to make the reaction less favorable.


How does mass effect the rate of reaction between liver and hydrogen peroxide?

The mass of liver affects the rate of reaction with hydrogen peroxide due to the availability of catalase, the enzyme responsible for breaking down hydrogen peroxide into water and oxygen. A larger mass of liver provides more catalase molecules, increasing the number of active sites for the reaction, which can enhance the reaction rate. Conversely, a smaller mass means fewer enzyme molecules, potentially slowing the reaction. Therefore, there is a direct relationship between the mass of liver and the rate at which hydrogen peroxide is decomposed.


What is the law of active mass?

This law relates rate of reaction with active mass or molar concentration of reactants. At a given temperature, the rate of a reaction at a particular instant raised to powers which are numerically equal to the numbers of their respective molecules in the stoichiometric equation describing the reaction." Active mass = molar concentration of the substance = (number of gram moles at the substance)/(volume in litres) = (w/M)/V=n/V
