Catalysts and Catalysis

Because usually enzymes can help catalyze more than one substrate although they are specific. Enzymes are reusable (within reason) but do eventually wear out. Enzymes are efficient and don't need to be large to carry out their aid in the rate of chemical reaction processes.

Enzymes are needed because they act as biological catalysts, speeding up chemical reactions in the body. They are essential for various cellular functions such as digestion, metabolism, and energy production. Without enzymes, many biochemical reactions would occur too slowly to sustain life.

A catalyst is a substance that helps a chemical reaction happen faster without suffering any change. An example sentence is: Because of the catalyst, the project ending early.

An enzyme is a type of biological catalyst, which means it speeds up chemical reactions in living organisms. Enzymes are specific to the reactions they catalyze and are usually proteins. Catalysts, on the other hand, are substances that speed up chemical reactions without being consumed in the process. Both enzymes and catalysts lower the activation energy required for a reaction to occur, increasing the rate of reaction.

Meat tenderizer is made up of protease enzymes, usually papain and bromelain, that attack the protein structure of meat and makes less tough or more tender. An enzyme is biocatalyst that is itself made of a highly structured protein or proteins thus making it a biochemical and organic material. A catalyst, on the other hand, will still speed up chemical reactions like an enzyme, but cannot be classified as a biochemical or organic material; a catalyst is an inorganic or non-biochemical material that will speed chemical reactions.

No, the liver tissue contains an enzyme, which are a type of catalyst. Enzymes are organic and are made in living organisms where as catalyst aren't made of carbon and are not made by living organisms.

False.

The activation energy of the reaction remains the same. Enzymes split up the reaction pathway into fewer steps, so that less activation energy is required at each step. This allows each step to occur at a lower temperature, or more quickly at the same temperature.

A catalyst is a substance that speeds up the rate of a chemical reaction. Catalysts work by lowering a reaction's activation energy.

A substrate is a reactant of an enzyme-catalyzed reaction.

"Catalyst" typically refers to a substance that increases the rate of a chemical reaction without being consumed in the process. It provides an alternate pathway for the reaction to occur, lowering the activation energy required. Catalysts play a crucial role in various industrial processes and biological systems.

D. substrate (a specific reactant acted upon by an enzyme is called the enzyme's substrate.)

Enzymes are biological catalysts that speed up chemical reactions in cells by lowering the activation energy required for the reaction to occur. They bind to specific substrate molecules and help facilitate the conversion of substrates into products. This process allows cells to efficiently carry out various biochemical reactions necessary for their survival and function.

A catalyst is a substance which alters the rate of a chemical reaction but is chemically unchanged at the end of the reaction. basically it increases or decreases the speed of a chemical or biological reaction, but it does not get itself involved in the reaction. hoped this helped (:

No, it is not. If a radionuclide has a half-life of 1 month, half is gone after 1 month. Half of the half that is left will be gone after 2 months, and that will leave 1/4th of the original amount left after the second month.

Living things depend on enzymes because enzymes are proteins that catalyze or speed up chemical reactions in the body. Enzymes are essential for processes such as digestion, metabolism, and cellular functioning. Without enzymes, these reactions would occur too slowly to sustain life.

An example of a biological catalyst is an enzyme. Enzymes are proteins that speed up chemical reactions in living organisms by lowering the activation energy required for the reaction to occur. They are specific in their action and can catalyze a wide range of biochemical reactions.

A catalyst is a chemical species that alters the rate of a chemical reaction without undergoing any type of change. Such catalysts that slow down a reaction are called negative catalysts or poison.

Amylolytic enzymes are a group of enzymes that break down starch molecules into simpler sugars like maltose, glucose, and maltotriose. They play a crucial role in various processes such as digestion in animals, brewing beer, baking bread, and producing ethanol. Examples of amylolytic enzymes include amylase, glucoamylase, and pullulanase.

An enzyme acts to speed up chemical reactions by lowering the activation energy required for the reaction to occur. It does this by binding to specific substrates and facilitating the conversion of reactants into products. Enzymes are specific in their function, often catalyzing only one type of reaction.

Proteins that act as biological catalyst are called enzymes.

YES AND NO.

Firstly: A polyepeptide is a protein, constructed of many amino acids, coded for by the genetic code. (in triplets).

A cell produces many polypeptides--in other words proteins.__ These proteins (polypeptides) each have a specific purpose/role in the cell.For example, hameoglobin is a polypeptide. Proteins are basically refererd to as polypeptides, as they consist of many amino acids bounded together. POLY= MANY. Of some of the polypeptides (proteins) some are enzymes.

Enzymes catalyse reactions. Their poltpeptide shape--tertiary structure enables them to do this, as they have an active site which binds to the substrate. Each enzyme catalyses a specific substate.

Anyway, i think that's all you need to know.

A positive catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. It lowers the activation energy needed for the reaction to occur, leading to faster reaction rates. Positive catalysts are also known as catalysts or promoters in chemistry.

Catalysts are used in industries to increase the rate of chemical reactions, reduce the amount of energy required for reactions to occur, and improve product yield. By providing an alternative reaction pathway with lower activation energy, catalysts can help save time and resources in industrial processes. Additionally, catalysts can be reused multiple times, making them cost-effective for large-scale production.

The enzyme action can be understand by different theories as: 1 Fischer's lock and key mechanism: This model was proposed by Emil Fischer in 1898. It is also called the tamplate model. According to this model the union of the substrate and the enzyme takes place at the active site more of less in a manner in which a key fits in a lock and results in formation of an enzyme substrate complex. And as the two molecules are involved this hypthesis is also known as the concept of intermolecular fit The ES complex is highly unstabe and almost immideately this complex decompose to produce the end product of the reaction and regenerate the free enzyme. The ES complex results in the release of energy. 2 Koshland's Induced fit model: This model was proposed by Koshland in 1958. He demonstrated that the enzyme molecule does not retain its original shape and structure. But the contact of the substrate induces some configuration or geometrical changes in the active site of the enzyme molecule. Consequnetly the enzyme molecule is made fit completely the configuration of active center of the substrate. At the same time other amino acid residue may become buried in the interior of the molecule. PROPERTIES OF ENZYMES: Enzymes are the protenious catalyst that increase the velocity of biochemical reactions and are not consumed during the reactions they catalysed. They like other catalyst work in specific temprature and pH range and also fit with only specific substrate with their active site. They can trigger the velocity of reaction by 103 to 108 times then uncatalysed reaction. They are some time asssociated with co factors like metals which help them in initiating the reaction.

The major organic product formed when 3-heptyne is hydrogenated in the presence of Lindlar's catalyst is 3-heptene. Lindlar's catalyst is a poisoned palladium catalyst that selectively reduces alkynes to cis alkenes.

Garbage enzymes can be made using kitchen scraps like fruit and vegetable peels, brown sugar, and water. These ingredients are fermented together in a container for a few months to create an enzyme-rich liquid that can be used as a natural cleaning agent or fertilizer.
