Text Solution

Verified by Experts
The correct answer is:
B

Each enzyme (E) has a substrate (S) binding site in its molecule so that a highly reactive enzyme-substrate complex (ES) is produced. This complex is short-lived and dissociates into its product and the unchanged enzyme with an intermediate formation of the enzyme-product complex (EP).
The formation of the ES complex is essential for catalysis.
