According to the lock and key model, the substrate acts as a:
Correct answer: A. Key
- A. Key
- B. Lock
- C. Both Options A and B are correct
- D. None of these options is correct
Explanation
Lock and key model assumes that like a particular key opens a particular lock, a specific enzyme (key) acts upon a particular substrate (lock).

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
