Key Concepts

Catalysis

Catalysis is the process of increasing the rate of a chemical reaction by introducing a catalyst, a substance that is not consumed during the reaction. In biological systems, enzymes serve as catalysts by facilitating the reaction pathways necessary for life.

Activation Energy

Activation energy is the minimum amount of energy required to initiate a chemical reaction. Enzymes reduce the activation energy barrier, allowing reactions to proceed more rapidly and under conditions that are compatible with life.

Enzymes

Enzymes are specialized protein molecules that speed up biochemical reactions by lowering the activation energy required. They play critical roles in metabolic pathways, ensuring that vital reactions occur efficiently under the mild conditions of living organisms.

Biological Catalysts

Being biological catalysts, enzymes accelerate chemical reactions in living systems without being consumed in the process. Their ability to repeatedly catalyze reactions makes them indispensable for processes such as digestion, energy production, and DNA replication.
