Question

Which of the following representation shows the correct steps in catalytic reaction of an enzyme?

• A. E + S $\to$ E + P
• B. E + S $\to$ ES $\to$ E + P
• C. E + S $\to$ EP $\to$ E + P
• D. E + S $\to$ ES $\to$ EP $\to$ E + P

Answer 1

The correct option is D E + S $\to$ ES $\to$ EP $\to$ E + P

The catalytic reaction of an enzyme can be described in the following steps:
E + S $\to$ ES $\to$ EP $\to$ E + P

1. Substrate binds to the active site of enzyme.
2. Formation of enzyme-substate complex.
3. Formation of enzyme-product complex.
4. Release of product from the enzyme.
