In short: Enzymes are the workhorses of life, but they often cannot function alone. This video explores the essential role of cofactors and coenzymes, the non-protein molecules required to catalyze the chemical reactions that sustain every living cell.

While enzymes are proteins, many require additional components to become active. These helpers are categorized into two main groups: cofactors and coenzymes. Coenzymes are specifically organic cofactors that assist enzymes in facilitating complex biochemical processes.

Understanding these mechanisms is fundamental to biology, as they represent the intricate systems that make life possible at the cellular level. The content is designed for high school or first-year college biology students seeking to understand the molecular machinery of life.
