Catalyst

Substance that lowers the activation energy of a chemical reaction and speeds up reaction time

Active site

Location in an enzyme where the chemical reaction takes place

Amylase

Digestive enzyme in saliva and the pancreas, involved in the digestion of starch

Coenzyme

Substances that help enzymes catalyze reactions

Enzymes

Macromolecular biological catalysts that accelerate chemical reactions

Induced fit

Change in shape of the active site of an enzyme so that it binds tightly to a substrate

Isomerase

General class of enzymes that convert a molecule form one isomer to another

Lactase

Family of enzymes involved in the hydrolysis of the disaccharide lactose, located in the brush border of the small intestine

Maltase

An enzyme hat catalyzes the hydrolysis of disaccharide maltose to glucose monomers

Sucrase/invertase

Enzyme that catalyzes the hydrolysis of sucrose into fructose and glucose monomers

Substrate

The substance upon which an enzyme reacts

Specificity

Phenomenon of enzyme shape determining the reaction the enzyme catalyzes
