Enzyme, a catalyst that regulates the rate at which chemical reactions proceed in living organisms without itself being altered in the process Most critically, enzymes catalyze all aspects of cell metabolism Learn more about enzymes in this article
- 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

Enzymes facilitate this by binding to a cell, creating the reactions needed to do things like digest food, clot blood, and grow With enzyme binding, chemical reactions can occur without destroying the cell 2 Enzymes aren’t used up in the reaction, so they can be used repeatedly

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
