Question

1. what is the name of the model given to the relationship between an enzyme and the substrate(s) it can bind to?

○ jigsaw puzzle
○ lock and key

○ peg and hole

Explanation:

This is a foundational concept in enzyme biochemistry. The lock and key model describes the specific, complementary fit between an enzyme's active site (the "lock") and its substrate (the "key"), where only the correct substrate can bind to the enzyme to initiate a reaction. The other options are not the standard scientific name for this relationship.

Answer:

lock and key
