Quiz

Which two substances bind using a lock-and-key mechanism?

A. enzyme and substrate
B. reactant and substrate
C. substrate and product
D. reactant and product



Answer :

Final answer:

Enzymes and substrates bind using a lock-and-key mechanism where their complementary structures fit together like a key in a lock.


Explanation:

Enzymes and substrates bind using a lock-and-key mechanism. In this model, the active site of the enzyme has a complementary structure to the substrate, allowing them to fit together like a key in a lock, forming the enzyme-substrate complex. This specific binding is crucial for the catalytic reaction to occur.
