Question

Which of the following statements is INCORRECT about the enzyme-substrate complex?

• A. It allows the enzyme to bind more tightly to the substrate.
• B. It helps break the chemical bonds within the substrate.
• C. Formation of the Enzyme-Product complex.
• D. It transforms the product back into the substrate.

Hint:

The complex converts substrate into product and never converts the product back into substrate.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept
When a substrate enters the active site, the enzyme changes shape slightly and grips the substrate more tightly (induced fit).

Step 2: Check the statements
In the complex the bonds of the substrate are strained and broken. The enzyme-substrate complex then becomes an enzyme-product complex.

Step 3: Find the false one
The complex does not transform the product back into the substrate. So statement (D) is incorrect.

Final Answer:
The incorrect statement is that the complex transforms product back into substrate. \[ \boxed{\text{(D) }\text{It transforms the product back into the substrate.}} \]
