The application of catalysts in life, the role of catalysts

Your liver secretes catalase every day. The catalytic capacity is 1,000 times that of ferric chloride. Flatten the hydrogen peroxide produced by your metabolism.

You have a lot of amylase in your saliva. Ultra-fast acceleration of starch decomposition. Convert to maltose.

You have pepsin in your stomach. Proteins can be broken down into amino acids.

These processes can be carried out without the action of these enzyme catalysts. Estimate. The decomposition rate is almost negligible.

Yes. Forgot to explain the catalyst.

The so-called catalyst can change the reaction rate. But a substance that does not change itself before and after the reaction.

By decreasing or increasing the activation energy. Most are to accelerate the reaction rate, by adjusting the energy required for the reaction. So that the reaction can be done at a lower energy level.

There are many types of catalysts. For example, manganese dioxide, a common inorganic substance, can catalyze potassium chlorate to produce oxygen. Iron chloride can catalyze the decomposition of hydrogen peroxide.

But the most powerful is the biological enzyme catalyst.

Think about it. Your body temperature is just over 36 degrees. Some reactions can only occur at high temperatures of 1,000 degrees.

Some reactions are so slow that you can't finish it even when you're dead. How can they be coordinated to react in the same environment at the same time? Only enzymes are used to catalyze regulation.

Reduced activation energy. Thousands of enzymes. Thousands of catalytic reactions.

It's already going crazy in your body when you look at my answers. Look for examples. You yourself are a big example.

A catalyst is a chemical substance that can change the reaction speed of a chemical reaction, but does not change the thermodynamic equilibrium position of the chemical reaction, and is not obviously consumed in the chemical reaction.

1. Accelerate the chemical reaction rate and improve the production capacity.

2. The catalyst only accelerates the reaction to equilibrium, and cannot change the equilibrium position of the reaction.

3. The catalyst has selectivity for the reaction, when the reaction has more than one different direction, the catalyst only accelerates one of them, and the reaction rate and selectivity are unified.

4. The life of the catalyst. The catalyst can change the rate of the chemical reaction, it does not enter the reaction itself, and ideally the catalyst is not changed by the reaction. In the actual reaction process, the catalyst will also undergo physical and chemical changes due to long-term heat and chemical reaction.

5. For complex reactions, you can choose to accelerate the rate of the main reaction, inhibit the side reactions, and improve the yield of the target product.

6. Improve operating conditions, reduce requirements for equipment, and improve production conditions;

7. Develop new reaction processes, expand the utilization of raw materials, and simplify the production process;

8. Eliminate pollution and protect the environment.

Catalysts are not the only ones, see what substances can also be used as catalysts for hydrogen oxide decomposition.

Catalyst action: CatalysisIn the catalytic reaction, the catalyst reacts with the reactants chemically, changing the reaction pathway, thereby reducing the activation energy of the reaction.

The phenomenon of accelerating or slowing down the rate of a chemical reaction due to the intervention of a catalyst is known as catalysis. In catalytic reactions, the catalyst interacts with the reactants and changes the reaction pathway, thereby reducing the activation energy of the reaction, which is the reason why the catalyst can increase the reaction rate.

For example, in the chemical reaction A+B AB, the required activation energy is E, and after adding catalyst C, the reaction is carried out in two steps, and the required activation energy is F and G respectively, where F and G are less than E.

Catalysis can be divided into the following types: homogeneous catalysis. The catalyst and reactants are both in the same phase for catalytic action, such as homogeneous acid-base catalysis, homogeneous complexation catalysis, etc.

Homogeneous catalysis is mostly carried out in the liquid phase. The active center of the homogeneous catalyst is relatively homogeneous, the selectivity is high, and the side reactions are few, but the catalyst is difficult to separate, ** and regenerate.

Heterogeneous catalysis. Catalysis that occurs at the interface of two phases. Usually the catalyst is a porous solid and the reactants are liquids or gases.

In heterogeneous catalytic reactions, the solid catalyst has a chemical adsorption effect on the reactant molecules, which activates the reactant molecules, reduces the activation energy of the reaction, and accelerates the reaction rate.

The surface of the solid catalyst is inhomogeneous, and only some points have chemical adsorption of reactant molecules, called active centers. Most of the catalytic effects in industrial production belong to heterogeneous catalysis.

Biocatalysis. Catalytic reactions carried out in organisms under the action of enzymes. The catalytic effect of enzymes has the characteristics of high selectivity, high catalytic activity, and mild reaction conditions, but it is greatly affected by factors such as temperature, pH value in solution, and ionic strength.

Autocatalysis. Autocatalysis of reaction products. In some reactions, the products or intermediates of some reactions have a catalytic function, so that the rate of the reaction is greatly accelerated after an induction period.

Autocatalysis is one of the necessary conditions for chemical oscillations to occur. Others include electrocatalysis, photocatalysis, photocatalysis, etc.

Summary. Proteases, lipases, and amylases digest what we eat and convert it into substances that the body can absorb.

The enzyme alcohol dehydrogenase in your liver helps metabolize the alcohol you drink.

Thank you. Thank you.

Proteases, lipases, and amylases digest what we eat, and turn them into substances that the body can absorb, and the state alcohol dehydrogenase in the liver can help metabolize the alcohol you drink.
