Protein Catalyst That Speeds Up The Rate Of Specific Biological Reactions (2023)

1. The Central Role of Enzymes as Biological Catalysts - The Cell - NCBI

A fundamental task of proteins is to act as enzymes—catalysts that increase the rate of virtually all the chemical reactions within cells.
A fundamental task of proteins is to act as enzymes—catalysts that increase the rate of virtually all the chemical reactions within cells. Although RNAs are capable of catalyzing some reactions, most biological reactions are catalyzed by proteins. In the absence of enzymatic catalysis, most biochemical reactions are so slow that they would not occur under the mild conditions of temperature and pressure that are compatible with life. Enzymes accelerate the rates of such reactions by well over a million-fold, so reactions that would take years in the absence of catalysis can occur in fractions of seconds if catalyzed by the appropriate enzyme. Cells contain thousands of different enzymes, and their activities determine which of the many possible chemical reactions actually take place within the cell.

Enzymes are proteins which catalyze, or 'speed up', chemical reactions. 'Speeding up', also known as catalysis, is the process by which the rate of a chemical reaction increases. Proteins, which are like the laborers of the cell, which catalyze chemical reactions are called enzymes. One example of an enzyme is glucosidase, which takes maltose, a disaccharide, and splits it up into two monosaccharides (glucose) much more quickly than a molecule of maltose could split into two glucose molecules independently.
