What did Fischer hypothesis concerning enzymes?
Catalyst theory
Lock and key mechanism
Protein denaturation
Enzyme inhibition
Answer
The Lock-and-Key Model, put forth by Emil Fischer, proposes that the active site of an enzyme exhibits a specific shape that perfectly accommodates and binds to the substrate molecule. This precise fit enables the enzyme to catalyze and enhance the rate of a specific biochemical reaction. The interaction between the enzyme and substrate resembles the way a key fits into its specific lock, illustrating their high degree of structural complementarity.
