Question

Transition state structure of the substrate formed during an enzymatic reaction is

• A. permanent but unstable
• B. transient and unstable
• C. permanent and stable
• D. transient but stable

Answer 1

The correct option is B transient and unstable

All enzymatic reactions go through a transition state. This state is in between the substrate and the product and has the highest energy. Therefore it is transient and unstable.
