Catalysts and Catalysis

Parent Category: Chemistry
Catalysts are compounds or elements which take part in a reaction without getting used up themselves.
something weird and cool happens to the enzyme when it is denatured. look it up yourself. i dont know the answer.
UOne way is to write it above the arrow that links reactants going to products
"Enzyme reactor" is a vessel in which a chemical reaction takes  place and is accelerated by catalysts classified as enzymes.
Essential nutrients for enzymes include calcium, phosphorus,potassium, sulfur, sodium, chlorine, and magnesium.
Enzymes are proteins that act as biological catalysts. Enzymes  increase the rate of chemical reactions like other catalysts.
They are biological catalysts and speed up reactions. They are used in washing powder and in some baby foods. They are also found in the body and help to break down some of the food groups:   protease- breaks up protein molecules, turns them into amino acids.   carbohydrase-breaks up...
The endoplasmic reticulum and ribosomes help to produce enzymes.
As most catalysts are quite specific in the (or at least the type of) reaction, in others not working at all, I can't give an answer for 'your acetone-reaction'. But to my best knowledge there are very few reactions I can think of being catalysed by acetone; never heard of, you know.
When a catalyst is added to a reaction the activation energy will decrease, becase the catalyst provides an alternative route for the reactants which requires less activation energy
The answer is coenzyme because it has nothing to do with speeding u chemical processes
Cracking , Cracking is the name given to breaking up large hydrocarbon molecules into smaller and more useful bits. This is achieved by using high pressures and temperatures without a catalyst, or lower temperatures and pressures in the presence of a catalyst.
yes MnO2 is an example anything that oxiidizes will break the H202 DOWN
A catalyst provides a reaction pathway with a lower activation energy and so directs the reaction one specific way or accelerates the reaction. An inhibitor blocks a reaction path and so prevents a product or slows down the reaction.
Biological catalysts are known as enzymes. Are proteins that have specific binding sites. Substrate interacts with the enzymes binding site via non covalent interactions (e.g hydrogen bonding). Enzymes can perform a variety of tasks on the substrate to allow for cleavage etc.
Organic catalysts (which sometimes mean "enzymes"), are usually proteins. One example of an organic catalyst that is NOT a protein is ribozyme.
Biological functionEnzymes serve a wide variety of functions inside living organisms. They are indispensable for signal transduction and cell regulation, often via kinases and phosphatases. They also generate movement, with myosin hydrolysing ATP to generate muscle contraction and also moving cargo...
A catalyst is something that speeds up a chemical reaction
A lump of solid has a much lower surface area compared to a powdered catalyst. Since most chemical reactions that are catalysed by solid phase catalysts (heterogeneous catalysts) occur on the catalyst surface more surface area = faster reaction.
Auto catalysts refer to automotive catalysts. They contain platinum palladium and rhodium for the most part. Catalytic converter scrap.
we did this in science, they increase the reaction. EG: blowing on a fire makes it burn better because u r feeding it more oxygen, a catalyst.
Enzymes are temperature-sensitive, inorganic catalysts are not.
Beneficial enzymes are SOD(super oxide dismutase), glutation peroxidase and catalase etc.
a reaction is said to be autocatalysed,if the reaction product is itself the catalyst for that reaction.     a reaction which is catalysed by its own reactants is called an auto catalyzed reaction and process is caleed as auto catalysis  
It depends upon the leaving group, that catalyst is suitable which has the attraction towards leaving group.
BASF Corporation. BASF Catalysts, formerly Englehard Corp, has recently (as of April 7, 2010) been renamed BASF Corporation.
Helicase splits the 3' and 5' Okazaki fragments, while the DNA polymerase attaches the "new" 3' nucleotide, with the "old" 5' nucleotide. As well as proofreading, or making sure that the bases are complementary in order to avoid mutations.
If your question is "What affects catalyst performance?" (i.e. what stops them from working) then there are 2 main things:Atoms permanently bonded to the surface, blocking it, and so that stops other reactant molecules from sticking to it (catalyst poisoning)Catalyst sintering: This can be seen on...
Enzymes are inside our cells in our body, they are meant there so we won't be sick and feel terrible, not only us but the cells protecting the enzymes are protecting us so we won't feel terrible, but it depends on how you help your body, the cells, and the enzymes.
  Only small quantity is need for a reaction   They are specific. One catalyst is need for specific reaction only   Physical properties may change during a reaction but no it does not take part in the reaction.
  the saliva contains enzymes
Without catalysts the majority of chemical reactions required for organisms to survive would not proceed fast enough or would require more energy than can be provided.
  enzyme purification is a process involve purification of protein depends on its unique structure, which determines both biological function and properties in solution
Catalysts don't get used up, we can use one forever without it getting used up. So they save a lot of money.
  Hey, try this website.   http://www.chemguide.co.uk/physical/catalysis/inorganic.html#top   Hope that helps. =]
  they speed up chemical reactions without changing the equilibrium position and without being permantly altered themselves
Light can affect the rate of a reaction by altering the speed of  the reaction. The more light there is, the faster the reaction  takes place.
  I don't think so as industrially in order to last, enzyme solutions are kept frozen and then defrosted immediately prior to use (not any later in order to optimise their activity).
Denaturation is the change in the three-dimensional structure of an enzyme or any other soluble protein,caused by heat or chemicals such as acids or alkalis.
Penicillin works by irreversibly inhibiting an enzyme (transpeptidase) that catalyzes a crosslinking reaction in the formation of the bacterial cell wall.Penicillin inhibits the transpeptidase by forming an irreversible covalent bond with the active-site serine residue in the enzyme
A catalyst is not actually used in a reaction it needs only to be there for the reaction to happen. so if you can isolate the catalyst as it leaves the system then it can be used again.
Simple answer : Enzymes are proteins. Slightly less simple answer : Enzymes are proteins that act as a catalyst in metabolism.
Common catalysts include manganese dioxide and silver.
A catalyst is a substance that changes the rate of a chemical  reaction without any permanent changes to its own structure.
turns maltose into glucose
  The overall enthalpy change in a common reaction would not change. Only the path to get there would change. A catalyst basically lessens the activation energy required to get the reaction to take place.
Catalysts lower the energy needed for a chemical reaction and are unchanged by the reaction. Since they are not changed, they can be reused indefinitely.
\nI am pretty sure Protease is, it is in most household cleaners.
Because of the following reasons :1- The big surface area of the silica gel (up to 800 square meter for one gram) .2- Silica gel ability to adsorb many other substances & compound which them self may acts as catalyst .3 - The high thermal ,chemical & deformation resistance of silica gel .4...
yes they do, enzymes are proteins that have catalytic power due to a certain arrangement of amino acids that knows how to recognize another and hydrolyse it. That is some of the reasonninng behind why chymotrypsin is produced as a zymogen because in theory (however its folding prevents it from self...

enzymes are molecules that help break own your food
  The helicase in a way unzipps the wound DNA. DNA Polymerase then matches the nucleotide bases with free floating one so that A matches with T (or in RNA U) and G matches with C. Creating two new strands of DNA and completing DNA replication.
No, an enzyme is a chemical that is in your body and breaks down food in your body. For example starch is broken down by the enzyme Lipase. Hope this helps. X
A catalyst can stop or speed a chemical reaction.
Essentially, catalysts speed up chemical reactions by reducing the amount of energy required for the reaction to occur. Catalysts are not consumed in the process, and so can do this many times. Some other factors that can affect a catalysts' ability to speed a process are temperature, concentration ...

In many organic and inorganic chemical reactions. See the link bellow for more details.
Can you recognize Cu nanoparticles without TEM microscopy?
enzymes are special proteins that are used as biological catalysts. they speed up chemical reactions in cells by lowering the energy needed for the reaction
In humans at least, enzymes are called bio-catalysts.  
A. Thermals A Conductor is a material which allows either heat or electricity to pass easily through it. A Catalyst is a material which speeds up a chemical reaction without being used up itself. An Enzyme is a biological catalyst, i.e. a catalyst which occurs in living things. Chemical Bond...
An acid catalyst is used can be in many forms such as sulfuric acid or ion-exchange resin.
That is the definition of a catalyst. A biological catalyst is known as enzymes.
A catalyst is something which speed up a chemical reaction without inself being used upin the reaction
Catalysts do not affect the equilibrium, they only speed up the reaction.
No the catalyst is not consumed in the reaction, this is part of the definition of a catalyst.
Catalysts are basically what starts the reaction. You need a catalyst to even get a reaction. Like a match for example. If you were trying to light \\a candle, you couldn't just light the candle without some source of fire to start it. That source of fire would be your catalyst. A match works great...
