NEET Zoology (general) MCQ Question
Type: MCQ-diagram based-Hard-Class 11
Consider a diagram showing the catalytic cycle of an enzyme. Which step correctly describes the transition from the enzyme-substrate complex (ES) to the enzyme-product complex (EP)?
A
The enzyme alters its shape to tightly fit the substrate, facilitating bond breaking.
B
The enzyme releases the substrate without any chemical reaction occurring.
C
The substrate detaches from the enzyme, leading to the formation of the transition state.
D
The enzyme binds to a different substrate to start a new reaction cycle.
Correct Answer
Option A
Detailed Explanation
The transition from ES to EP involves the enzyme altering its shape to fit more tightly around the substrate, which facilitates the breaking of chemical bonds as per the catalytic cycle described.
