Catalytic Site Vs Active Site -

1. Introduction: The Vocabulary of Enzyme Function Enzymes are biological catalysts that accelerate chemical reactions with remarkable specificity and efficiency. To understand how they work, we must precisely describe the molecular regions responsible for their function. Two terms dominate this discussion: active site and catalytic site .

Understanding this difference allows you to ask the right questions: “Does this mutation abolish binding (active site defect) or just slow chemistry (catalytic site defect)?” – a distinction that can mean the difference between a non-functional enzyme and one with altered specificity. catalytic site vs active site
