Catalysts

Definition

Catalysts are substances that speed up chemical reactions without being consumed in the process.

Scientific / Technical Definition

In biochemical terms, catalysts, often specific proteins known as enzymes, play a critical role in facilitating biological reactions by lowering the activation energy required for the reaction to proceed, thereby increasing the reaction rate.

Benefits

• Facilitate essential metabolic processes.
• Support efficient energy production in cells.
• Enable the breakdown and synthesis of vital molecules.

Examples

• Enzymes like catalase and peroxidase found in almost all living organisms.
• Enzymes in digestive juices that help break down food in the human body.

Additional Information

• Importance: Catalysts, particularly enzymes, are crucial for maintaining life functions by enabling biochemical reactions to occur at a rate sufficient for sustaining life.
