Enzymes
Table of Contents
Enzymes /ˈɛnzaɪmz/ are both proteins and biological catalysts (biocatalysts). Catalysts accelerate chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products. Almost all metabolic processes in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life.[1]:8.1 Metabolic pathways depend upon enzymes to catalyze individual steps.
Several enzymes can work together in a specific order, creating metabolic pathways.[1]:30.1 In a metabolic pathway, one enzyme takes the product of another enzyme as a substrate. After the catalytic reaction, the product is then passed on to another enzyme. Sometimes more than one enzyme can catalyze the same reaction in parallel; this can allow more complex regulation. Enzymes determine what steps occur in these pathways. Without enzymes, metabolism would neither progress through the same steps and could not be regulated to serve the needs of the cell.

List of Enzymes and Functions in the Body
Examples of Enzymes – and Functions in the Body
- Digestive: Amylase, Trypsin, lipase.
- Metabolic: Oxidase, hydrolases, lygases, cytochrome -450
- Liver: Serum glutamic oxaloacetic transaminase (SGOT), Serum glutamic pyruvic transaminase (SGPT).
- Nucleases: Topoisomerase, endonuclease, DNA polymerase
- Receptor enzymes: These are enzymes which are part of certain types of receptors. Ex: phosphokinases,
