In the lock-and-key hypothesis of enzyme action, what component represents the 'lock'?
Understand the Problem
The question is asking about the lock-and-key hypothesis of enzyme action and which component represents the 'lock'. This model is used to explain how enzymes and substrates interact.
Answer
The enzyme represents the 'lock'.
In the lock-and-key hypothesis of enzyme action, the enzyme represents the 'lock'.
Answer for screen readers
In the lock-and-key hypothesis of enzyme action, the enzyme represents the 'lock'.
More Information
The lock-and-key model, introduced by Emil Fischer in 1894, illustrates how an enzyme's active site has a shape that only allows a specific substrate to bind, similar to a lock only accepting a specific key.
Tips
A common mistake is confusing the roles of the enzyme and substrate in the lock-and-key model. Remember, the enzyme is the 'lock' and the substrate is the 'key'.
