Interlock
Enzymes and their specific substrates fit together like a lock and key. Enzymes have specific binding sites that perfectly match the shape of their substrates, allowing for efficient catalysis of specific chemical reactions. This lock-and-key model is essential for the specificity and efficiency of enzyme-substrate interactions.
The lock and key model means that the substrate must perfectly fit the enzyme, and the enzyme does not change. The induced fit model is different as when the substrate fits together with the enzyme, the enzyme itself will change to either join substrates together or break a substrate down.
The key and lock theory suggests that enzymes and substrates fit together like a key fits into a lock with a rigid, non-flexible active site. In contrast, the induced fit model proposes that the enzyme's active site can change its shape to accommodate the substrate, thus providing a more dynamic interaction between the enzyme and substrate.
A substrate and its enzyme are like a lock and key because they have specific shapes that fit together perfectly. Just like a key must fit exactly into a lock to open it, the substrate must fit into the enzyme's active site for a reaction to occur. This specific interaction ensures that only the correct substrate is acted upon by the enzyme.
The lock and key hypothesis explains enzyme functioning. It suggests that enzymes and substrates fit together like a lock and key, with specific enzyme-active sites binding to specific substrates to catalyze reactions.

A map of the continents (with the exclusion of Antarctica and the inclusion of Greenland) is included in the link below and depicts how they would fit together today. They do not completely lock perfectly as their coasts have been eroded.
Gears are wheels with teeth that fit together.
To properly mortise a door for a new lock, use a chisel and hammer to create a recess in the door that matches the size and shape of the lock. Make sure the mortise is deep enough for the lock to fit securely. Test the fit of the lock before installing it to ensure it sits flush with the door surface.
An example of the induced fit theory is when an enzyme undergoes a conformational change to better accommodate the substrate upon binding. On the other hand, the lock and key theory suggests that the enzyme's active site is already in the correct shape to fit the substrate like a lock and key.
If you want the very best lock that will fit on a school locker I would recommend the Master Lock 185D. It is a keyed lock, not a combination lock. It is a very high security lock that is vandalism-resistant and is not easily cut or shimmed.
