It's a model used to describe one specific object fitting into another specific receptor; such as using a key on a lock that's how it gets its name. This is used to describe many things mainly cells and their receptors
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.
The induced fit model is considered better than the lock and key model because it takes into account the dynamic nature of enzymes and substrates, allowing for more flexibility in enzyme-substrate interactions. This model suggests that both enzyme and substrate undergo conformational changes to better fit each other, resulting in higher specificity and efficiency of the enzyme-substrate complex. Overall, the induced fit model provides a more accurate representation of the enzyme-substrate interaction compared to the rigid lock and key model.
A lock and key system works by using specially designed grooves and ridges on the key that align with pins inside the lock. When the correct key is inserted, the pins are lifted to the right height, allowing the lock to be turned and opened. This mechanism ensures that only the correct key can operate the lock.
Yes, a lock and key system can be considered a first-class lever because the key acts as the effort, the lock as the fulcrum, and the door as the load. Turning the key applies a force at a distance from the fulcrum to open the lock and move the door.
Both the lock and key model and induced fit model are mechanisms used to describe enzyme-substrate interactions. Both models explain how enzymes bind to substrates to facilitate chemical reactions. They both highlight the specificity of enzyme-substrate interactions.

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.
A key that doesn't fit in a keyhole is one that is either the wrong shape, size, or design for that particular lock. For example, a car key won't fit in a house door lock due to differences in their shapes and mechanisms. Similarly, a broken or bent key may also fail to unlock a lock even if it's meant for that specific keyhole.
Yes, a locksmith can rekey a lock for you by changing the internal pins and springs to fit a new key, rendering the old key ineffective.
A key fits into a lock, which is a mechanical device designed to secure doors, cabinets, or other objects. When the correct key is inserted into the lock, it aligns the internal components, allowing the lock to open. Keys can also fit into various types of mechanisms, such as ignition systems in vehicles or keyholes in safes.
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.
Key blanks are used to make keys from. Cutting the particular notches to make it fit a certain lock is what turns a key blank into a key.
Both the lock and key and induced fit models describe how enzymes interact with substrates to facilitate biochemical reactions. In the lock and key model, the enzyme's active site is a perfect fit for a specific substrate, much like a key fitting into a lock. In contrast, the induced fit model suggests that the enzyme's active site is flexible and can change shape to better accommodate the substrate upon binding. Despite these differences, both models emphasize the importance of the enzyme-substrate interaction in catalyzing reactions.

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 answer is lock and key model .
I was afraid that the key would not work because it was such a loose fit in the lock.
