Enzyme - Wikipedia
An enzyme is a biological macromolecule, usually a protein, that acts as a biological catalyst, accelerating chemical reactions without being consumed in the process. The molecules on which enzymes act are called substrates, which are converted into products. Nearly all metabolic processes within a cell depend on enzyme catalysis to occur at biologically relevant rates. [1]: 8.1 A metabolic ...

Enzyme - National Human Genome Research Institute
An enzyme is a biological catalyst and is almost always a protein. It speeds up the rate of a specific chemical reaction in the cell. The enzyme is not destroyed during the reaction and is used over and over. A cell contains thousands of different types of enzyme molecules, each specific to a particular chemical reaction.

What Are Enzymes and Why Are They Essential for Life?
Enzyme replacement therapy, for example, provides patients with functional versions of missing enzymes. Inhibitors that block harmful enzyme activity are used to treat diseases like hypertension, HIV, and cancer.

Enzymes: What They Are and How They Work - Verywell Health
Enzymes are substances in the body that cause and speed up crucial chemical reactions. Enzymes’ function is to help trigger bodily processes ranging from digestion to blood clotting to growth. There are many types of enzymes, and most enzymes are proteins. If you’re missing a certain type of enzyme or have too little of it, that can lead to health conditions that can be serious.

Enzymes: Structure, Types, Mechanism, Functions
What are Enzymes? An enzyme is a protein biomolecule that acts as a biocatalyst by regulating the rate of various metabolic reactions without itself being altered in the process.
