Enzyme Catalyst

Enzymes catalyze reactions by reducing the activation energy required for the reaction to proceed, stabilizing the transition state, and properly orienting the substrate molecules. This results in a significant increase in reaction rates, allowing biological processes to occur efficiently under mild conditions.

What is the mechanism by which enzymes catalyze reactions?

The non-protein component of an enzyme is known as a cofactor. Cofactors can be further classified into two main types: Coenzymes: Organic molecules that bind to the enzyme and assist in enzyme activity. They are often derived from vitamins and are usually loosely attached to the enzyme. Examples include NAD+ (nicotinamide adenine dinucleotide) and FAD (flavin adenine dinucleotide). Metal Ions: Inorganic ions that are essential for the activity of some enzymes. They can be tightly bound (as part of the enzyme structure) or loosely bound. Examples include magnesium (Mg²⁺), zinc (Zn²⁺), iron (Fe²⁺ or Fe³⁺), and copper (Cu²⁺).

Exam information

The catalysis in which enzymes act as a catalyst is called enzyme catalysis. Enzyme Catalysts are complex nitrogenous proteins that help to catalyze the biochemical reactions in living organisms. Learn about enzymes in detail.
