Compare catalysts inhibitors and enzymes
Both catalysts and enzymes lower the activation energyof a reaction thereby increasing its rate. A catalyst can be positive (increasing reaction rate) or negative (decreasing reaction rate) in nature. They react with reactants in a chemical reaction to give rise to intermediates that eventually release the product … See more Catalysis reactions have been known to humans for many centuries but they were unable to explain the occurrences they were seeing all around them like, fermentation of wine … See more Catalystsare used in energy processing; bulk chemicals production; fine chemicals; in the production of margarine and in the environment where they play a critical role of chlorine free … See more A catalyst is any substance that can cause significant alterations to the rate of a chemical reaction.

Enzymes are biological … WebAn enzyme's K m describes the substrate concentration at which half the enzyme's active sites are occupied by substrate. A high K m means a lot of substrate must be present to saturate the enzyme, meaning the enzyme has low affinity for the substrate. On the other hand, a low K m means only a small amount of substrate is needed to saturate the ...
