catalyst
A substance that speeds up a chemical reaction without undergoing a permanent change itself is a catalyst.
In Biology, a catalyst is a substance which speeds up a chemical reaction, without being changed themselves. Biological catalysts are found in living organisms.
This could refer to a chemical transformation (chemical change), a chemical reaction, or spontaneous change. Some changes require another substance or substances to be mixed together. Some reactions will occur by themselves without any outside manipulation or stimulation.
A catalyst.
In biological systems an enzyme speeds up the reaction without changing it. In other chemical reactions this function is achieved by a catalyst.
This is a catalyst
This is a catalyst
A substance that will increase the rate of a chemical reaction without becoming part of the products or being consumed in the reaction.
A catalyst is a substance that speeds up a chemical reaction without being consumed by it.
ENzyme
enzymes are never consumed in a chemical reaction, therefore the answer to your question is that enzymes that affect the speed of a chemical reaction without being consumed are indeed called enzymes.
A catalyst is a chemical that facilitates a chemical reaction between two other chemicals without being consumed in the reaction itself.
Catalyst
A (any) substance that expidites a chemical reaction without being part of it. The word is also used to mean anything that moves something along without being consumed.
A substance that speeds up a chemical reaction without undergoing a permanent change itself is a catalyst.
Do you mean Catalysts? If you do, then its any substance that increases the rate of a reaction without itself being consumed.
No, in order for a chemical reaction to take place, a new chemical substance must be formed.
