The lock-and-key mechanism refers to
A. the complementary shapes of an enzyme and a substrate.
B. the attractive forces between an enzyme and a substrate.
C. the ability of an enzyme to lower the activation energy of a reaction.
D. the ability of an enzyme to "unlock" the products of a reaction.
Answer (2)
The lock-and-key mechanism describes how an enzyme's active site and its substrate have complementary shapes, allowing for a specific interaction. This specificity is essential for the enzyme to lower the activation energy and facilitate biochemical reactions. The correct option is the first one provided. ;
The lock-and-key mechanism describes how the specific shapes of an enzyme and its substrate fit together, allowing for efficient biochemical reactions. This specificity is essential for enzyme activity, as it ensures that only the correct substrate can bind and undergo a reaction. The correct option is A, the complementary shapes of an enzyme and a substrate.
