What is the role of the active site in enzyme action?
Options
- ATo break the chemical bonds of the substrate
- BTo form the ES complex
- CTo induce the enzyme to alter its shape
- DTo release the products of the reaction
Correct answer
A. To break the chemical bonds of the substrate
Step-by-step solution
First, the substrate binds to the active site of the enzyme, fitting into the active site. The binding of the substrate induces the enzyme to alter its shape, fitting more tightly around the substrate. The active site of the enzyme, now in close proximity of the substrate breaks the chemical bonds of the substrate and the new enzyme- product complex is formed.
