Multiple Choice
In the enzyme-catalyzed reaction sequence E + S ⇌ ES → E + P, which component is released from the enzyme’s active site as the reaction proceeds?
A
Enzyme-substrate complex (ES)
B
Product (P)
C
Substrate (S)
D
Enzyme (E)
Verified step by step guidance1
Identify the components involved in the enzyme-catalyzed reaction: E (enzyme), S (substrate), ES (enzyme-substrate complex), and P (product).
Understand the reaction sequence: the substrate (S) binds to the enzyme (E) to form the enzyme-substrate complex (ES), which then undergoes a chemical transformation.
Recognize that during the reaction, the substrate is converted into the product (P) while still bound to the enzyme's active site.
After the chemical transformation, the product (P) is released from the enzyme's active site, freeing the enzyme (E) to catalyze another reaction cycle.
Conclude that the component released from the enzyme’s active site as the reaction proceeds is the product (P).
