Enzymes are general catalysts in the cell. They catalyse almost all reactions. They are proteins, some with other groups or ions attached.

What does it mean if enzymes are organic catalyst?
Enzymes are organic catalysts. A catalyst is a chemical that controls the rate of a reaction, but is itself not used up in the process. Reactions that are accelerated due to the presence of enzymes are known as enzyme-catalyzed reactions.
Is manganese dioxide a catalyst?
Enzymes are boilogical catalysts or assistants that speed up chemical reactions with out changing all enzymes are catalysts but not all catalysts are enzymes.Manganese oxide is not an enzyme but is a catalyst it is also a mineral. Thank you.
Why is hydrogenation with a catalyst considered an addition reaction?
It doesn't. Catalysts merely speed reactions along, they do not make them happen - that is the definition of a catalyst. Industrially, catalysts are important in making chemical reactions economically fast.
What element speeds up chemical reactions?
1) Something that speeds up a chemical reaction but that is not changed by the reactions is called a catalyst.2)An element is a pure substance (not a compound) and while some elements (such as platinum) can speed up chemical reactions (eg platinum in a car exhaust catalytic converter), by far the most common catalysts are in fact compounds not elements. These compounds are organic in nature and called enzymes.
Prosthetic group of enzyme is organic or inorganic?
No. Enzymes are ORGANIC catalysts. Enzymes are types of protein that are very similar to inorganic catalysts. Both increase the rate of a reaction (while decreasing activation energy.) Also, neither of them are used up or changed in the reactions that they speed up. A difference between the two is that enzymes are complex proteins but catalysts are simple inorganic molecules. The main difference is the way that the two are affected by temperature. Like other proteins, an increase in temperature causes an enzyme to denature and change shape. The shape of an enzyme is essential for its role in the reaction because it must fit with the specific substrate (the thing that it is helping to break down/speeding up the reaction of). Therefore, the enzyme will not speed up the reaction if it is denatured and no longer is the same shape. An inorganic catalyst, on the other hand, is more effective at a higher temperature and increases the reaction rate even more.

Why are catalysts used in organic reactions?
In organic reactions, catalysts are used to speed up the reaction taking place. For example, an enzyme can break down a substance in 3 seconds, which would take 1,000,000 years to break down with the absence of the enzyme. [The organic compounds are covalently bonded and overlapping of linearly and parallelly also take place so ,it is required the catalyst to accelerate the rate of chemical reactions].?
How do enzymes affect the rate of reaction?
Enzymes speed up a reaction but they are not changed by the reaction. They are a protein molecule that helps other organic molecules enter into chemical reactions with one another but is itself unaffected by these reactions. In other words, enzymes act as catalysts for organic biochemical reactions.
Are vitamins organic growth factors?
Vitamins would better be categorized as catalysts (to help chemical reactions in plants and animals). "Organic" has to do with whether it is carbon-based (at least in chemistry it does). Not sure what you mean by "Growth Factors"...
Metabolic reactions require organic catalysts called?
Metabolic reactions require organic catalysts called enzymes. These enzymes lower the activation energy of the reaction, thus increasing its reaction rate.
How does enzymes speed up chemical reactions?
The way enzymes speed up chemical/biochemical reactions is the same way that catalysts work. They provide an alternate pathway for the reaction which has a LOWER activation energy. They don't actually decrease the activation energy of the pathway in question, but rather they provide a different pathway that has a lower energy of activation.
What are a special group of proteins that speed up reactions are called?
They are called "Enzymes" or organic catalysts.
Which of these organic molecules function as catalysts for chemical reactions in living organisms?
Yes, they are called enzymes. Not only do they enhance the rate of the specific chemical reaction, also they do this with "a 100% YIELD" - that is (i. e.) with no waste byproducts! { The True Source of Their Power }
