Enzyme vs. Catalyst

Enzymenoun

(biochemistry) A globular protein that catalyses a biological chemical reaction.

Enzymenoun

(Christianity) leavened bread, as opposed to azyme

Enzymenoun

A protein produced by a living organism, capable of catalyzing a chemical reaction. Almost all processes in living organisms require some form of enzyme to cause the reactions to occur at a rate sufficient to support life. There are a very wide variety of enzymes, each specifically catalyzing a different chemical reaction, the sum of which cause the bulk of the physiological changes observed as life processes. Enzymes, like most proteins, are synthesized by the protein-synthetic mechanism of the living cell, at special sites on ribosomes, using the genetic information in messenger RNA transcribed from the genetic instructions stored as nuleotide sequences in the DNA (or in some viruses, the RNA) of the genome. Some examples of enzymes are: pepsin, diastase, rennet, DNA polymerase, invertase, glucose oxidase, protease, and ribonuclease. There are many other types of enzyme.

Enzymenoun

any of several complex proteins that are produced by cells and act as catalysts in specific biochemical reactions

Enzyme

Enzymes () are proteins that act as biological catalysts (biocatalysts). Catalysts accelerate chemical reactions.

Catalystnoun

(chemistry) A substance that increases the rate of a chemical reaction without being consumed in the process.

Catalystnoun

Someone or something that encourages progress or change.

Catalystnoun

(literature) An inciting incident that sets the successive conflict into motion.

Catalystnoun

(automotive) A catalytic converter.

Catalystnoun

a substance that initiates or accelerates a chemical reaction without itself being affected; as, thousands of enzymes serve in concert as calaysts to produce the sequence of reactions we call "life"; the industrial production of cheap ammonia depended on finding a good catalyst.

Catalystnoun

something that serves as a precipitating occasion for an event; as, the invasion acted as a catalyst to unite the country.

Catalystnoun

something or someone that causes events to happen with itself being changed.

Catalystnoun

(chemistry) a substance that initiates or accelerates a chemical reaction without itself being affected

Catalystnoun

something that causes an important event to happen;

Catalystnoun

a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change

Catalystnoun

a person or thing that precipitates an event
