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.
What else can I help you with?
An example of a biological catalyst?
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.
What are anti enzymes?
Anti enzymes or enzyme inhibitors, are substances which inhibit counteracts the action of an enzyme.
How many times can one enzyme be used?
Each enzyme molecule is used over and over again. One of the fastest enzymes is catalase, which is found in liver and elsewhere. It catalyzes the breakdown of hydrogen peroxide into water and oxygen: 2H2O2 forms 2H2O + O2 Each molecule of catalase catalyzes the breakdown of some 40 million substrate molecules in a second.

What is the mechanism of action of salicylamide in inhibiting the enzyme N-acetylglucosaminidase (NAI)?
Salicylamide inhibits the enzyme N-acetylglucosaminidase (NAI) by binding to the active site of the enzyme and blocking its function, thereby preventing the enzyme from carrying out its normal biochemical reactions.
What has the author M R Hollaway written?

What is the action of a catalyst in a chemical reaction? In this sentence, you're asking what the catalyst does. The chemical reaction only takes place because of action by the catalyst. In this sentence, you are essentially saying the same thing, but you don't put "the" in front of "action".

What kinds of chemicals might you add to try to speed up the action of an enzyme or to inhibit its action?
To speed up the action of an enzyme, you can add cofactors or coenzymes that are required for the enzyme's activity. Inhibitors can be used to block or reduce the enzyme's activity, such as competitive inhibitors that compete with the substrate for the active site, or non-competitive inhibitors that bind to another part of the enzyme and alter its shape.
