3.  Also known as Biocatalysts
“Enzymes are biocatalyst that accelerate the various cellular
reactions without any change during reaction”
 Catalytic substances produced by living cells
 Every cell synthesizes own enzymes
 Single cell contain as many as 10,000 enzymes
 Without enzyme no life
 Activators and key of life
 C, H, S, N & O in their structure
 Its molecular weight runs from thousand to million

4.  Proteinous in nature
 Accelerate the rate of reaction
 Not changing reaction state
 Required in minute quantity
 Not consumed in overall reaction
 Act as catalyst
 Responsible for lowering the activation energy
