Enzymes

Substance that speeds up the rate of a chemical reaction

A substance produced in a chemical reaction

Product

Large organic compounds that enzymes are made from

A change in the shape of a protein (such as an enzyme) that can be caused by changes in temperature or pH (among other things).

Denature

Reactant of an enzyme-catalyzed reaction:

Temperature at which an enzyme works the best

A substance that slows down or stops a chemical reaction

Three factors that affect enzyme activity:

Specific part of an enzyme where a substrate fits:

Active site

The minimum amount of energy required to start a chemical reaction

activation energy
