What Are Enzymes?

What are enzymes?

Enzymes are proteins which act as catalysts. They are not consumed in chemical reactions, but are used to accelerate them. Chemical reactions take a certain amount of energy to initiate. This is called the activation energy. Enzymes, while not participating in the chemical reactions themselves, lower this energy and thus make it easier for the reaction to initiate. They can also take reactions with high activation energies and split them into multiple steps with lower energies.

There are various factors that can determine how effective an enzyme performs. These include the amount of enzyme, the pH of the environment (inside the body), temperature, and the type of substrate and its concentration (proteins, fats, and carbohydrates).
