Answer:
changes the rate of chemical reaction, but it does not chemically change at the end of the reaction. The term catalyst originally originates from catalysis and means the change in chemical reaction rate. Unlike other materials, the catalyst may be involved in many chemical transformations, but it is not consumed in the reaction itself. This means that when catalyst is added to two materials to increase the reaction rate between them, the catalyst can be reused without being consumed. ([3] "Chem 4 Kids.com: reaction: catalyst and inhibitor") For example,
In the 19th century, chemists discovered that chemical reactions accelerated by adding certain chemicals (called catalysts). These catalysts are not consumed by the reaction and can be reused. Burton and Humphreys initially attempted to decompose oil using an aluminum chloride catalyst, but this catalyst proved to be uneconomical and both turned to thermal decomposition. Houdry believes that the next major step in purification is finding catalysts for the economy. Like Edison looking for the right filament, Houdry tried hundreds of possible catalysts. Finally, in 1927, Houdry discovered that oxides of silicon and aluminum destroy heavy petroleum molecules flowing through them. Houdry proved that broken gasoline is as good as the best petrol in the market in this way.
In this experiment, the deeper meaning of the reaction catalyst was investigated. The catalyst promotes the chemical reaction without permanently altering the reaction. Catalysts in biochemical reactions are globular proteins that reduce the activation energy required to initiate the reaction, thereby increasing the rate at which effective reactions occur. A protein (hereinafter referred to as an enzyme) is a complex molecule consisting of amino acids in a polypeptide chain in which peptide bonds are bonded to each other. The structure of the protein is broken down into primary, secondary, tertiary and quaternary structures and forms a complex structure that can be separated and identified by paper chromatography, or more importantly by spectrophotometric determination of protein concentration in aqueous solution .
Enzymes are catalysts involved in biochemical reactions. They are each of us "dwarfs", naming them to name thousands of such amino acids to form DNA by combining molecules like nucleotides, or to make proteins. As they are very important to life, scientists are not satisfied with calling them a catalyst and must invent a new name "enzyme". It turned out that adding a magical gnome makes the generation of red - red and blue - blue "molecules" faster. Another way to achieve the same speedup is to shake the bottle more strongly. This does not affect alignment as gnome, but increases the total number of collisions between red and blue that occur every second - rocks everything in the environment more violently. Increases in total collisions per second increase, as well as probability, the number of correctly aligned collisions also increases.
