Enzymes

A biological catalyst that speeds up chemical reactions in living organisms without being consumed in the process.

The specific region on an enzyme where the substrate binds and the reaction occurs.

The reactant molecule that an enzyme acts upon during a chemical reaction.

A model that explains how enzymes and substrates fit together; the substrate (key) fits into the active site (lock) of the enzyme.

A model that describes how the active site of an enzyme changes shape to better fit the substrate upon binding.

The substances that are formed as a result of the enzymatic reaction, located on the right side of the reaction arrow.

-ase, indicating that the molecule is an enzyme.

They lower the activation energy required for reactions, thus increasing the rate of the reaction.

Temperature, pH, substrate concentration, and the presence of inhibitors or activators.

A site on an enzyme other than the active site where molecules can bind, influencing the enzyme's activity.
