Enzyme - Wikipedia
https://en.wikipedia.org/wiki/Enzyme
WEBEnzymes ( / ˈɛnzaɪmz /) are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products.

WEB2 days ago · Definition. 00:00. … 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.
