Amylase (ptyalin)
Restriction enzymes.

In enzyme-catalyzed reactions, the term "substrate" is synonymous with the molecule or molecules that the enzyme acts upon to produce a reaction. It is the specific substance upon which an enzyme acts to produce a product.
Parietal cells in the stomach lining produce pepsinogen, the precursor enzyme of hydrochloric acid. Pepsinogen is converted into pepsin, the active enzyme that helps break down proteins in the stomach.
Protease is a protein-degrading enzyme produced in the pancreas.
The enzyme luciferase works in conjunction with ATP to produce bioluminescence. Luciferase catalyzes the oxidation of luciferin in the presence of ATP, resulting in light production.
The enzyme function would not be as effecient, causing the liver to produce more enzymes.
In most cases of lipidoses, the body does not produce a certain enzyme or chemical.
the enzyme, lactase
cytoplasm
Non-working enzyme → no ATP → no energy → death.
