Enzymes (/ ˈ ɛ n z aɪ m z /) are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products.
Enzymes are substances that act as catalysts in living organisms, regulating the rate of chemical reactions without being altered. Learn about the chemical nature, nomenclature, and mechanism of enzyme action, as well as their applications and examples.
Learn what enzymes are and how they speed up biochemical reactions in living things. Explore the definition, types, and examples of enzymes and their catalytic action.
A substance that helps a chemical reaction to occur is a catalyst, and the special molecules that catalyze biochemical reactions are called enzymes. Almost all enzymes are proteins, made up of chains of amino acids, and they perform the critical task of lowering the activation energies of chemical reactions inside the cell.

Enzymes are proteins or RNA molecules that help speed up chemical reactions in the human body. They are essential for various functions, such as digesting food, breaking down toxins, and producing energy. Learn about the basics, the perfect conditions, the cofactors, the inhibition, and the types of enzymes.
Enzymes are biological catalysts that accelerate chemical reactions by lowering the activation energy. Enzymes are proteins consisting of one or more polypeptide chains. Enzymes have an active site that provides a unique chemical environment, made up of certain amino acid R groups (residues).
Learn what enzymes are, how they lower activation energy, and how they bind to substrates. Explore the structure and function of enzymes, and how environmental factors affect their activity.
Explain how enzymes are classified and named. A catalyst is any substance that increases the rate or speed of a chemical reaction without being changed or consumed in the reaction. Enzymes are biological catalysts, and nearly all of them are proteins. The reaction rates attained by enzymes are truly amazing.
Key Terms. Enzyme structure and function. Enzymes are catalysts. They are usually proteins, though some RNA molecules act as enzymes too. Enzymes lower the activation energy of a reaction - that is the required amount of energy needed for a reaction to occur.
