According to lock and key model both the enzymes and the substrate possess specific geometrical shapes that fit exactly into one another.
WHILE
According to the induced fit model enzymes are more flexible structures and their active site is reshaped as substrate interacts with the enzymes.
the difference between the two is that the lock and key must fit perfectly. the induced fit will change over time.

How does the induced fit model help to explain non-competitive inhibition?
The induced fit model is the theory that instead of enzymes and substrates fitting exactly together, as in the lock and key model, the enzyme changes shape around the substrate to bind with it. Non-competitive inhibition is where the inhibitor does not fit into the active site, but into another site on the enzyme instead, which changes the shape of the active site.
What is a induced fit hypothesis?
a. The substrate can be altered so it is induced to fit into the enzyme's active site. b. The enzyme changes its shape slightly as it binds to the substrate. c. The enzyme is altered so it is induced to fit many different types of substrate. d. Several sites on an enzyme can be induced to act on a substrate.
When are scientific ideas modified-?
Scientific ideas are modified when evidence is found that does not fit the predictions. The scientists determine why and revise the model to fit the new data.
Difference between clearence fit transiton fit and interference fit?
clearance Fit - if the clearance is more between the mating parts then it is known as clearance fit. Transition Fit- If the clearance is less between the mating parts then it is known as Transition fit Interference Fit- If the mating parts are fouling or interfering.then it is known as Interference Fit
Can 60000 people fit on an island 15 miles across?
Yes. 60,000 people can fit in 4 miles so over 900,000 can fit over 15 miles. And 15,000 people can fit in 1 mile
What type of model does an enzyme work like?
enzymes work on lock and key model and induced fit model.
What is the difference between the lock and key model versus the induced fit model of the enzyme substrate complex?
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.
Why is the Induced fit model better than the lock and key model?
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.
What is the difference between the key and lock theory and the induced fit model?
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.
What is considered a model for enzyme?
the answer is lock and key model .
How are the ''lock and key'' and ''induced fit'' models similar?

How are the lock and key and induced models similar?
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.
How does the induced fit model help to explain non-competitive inhibition?
The induced fit model is the theory that instead of enzymes and substrates fitting exactly together, as in the lock and key model, the enzyme changes shape around the substrate to bind with it. Non-competitive inhibition is where the inhibitor does not fit into the active site, but into another site on the enzyme instead, which changes the shape of the active site.
What is the Best way to illustrate the way an enzyme interacts with another molecule?
A common and effective way to illustrate the interaction of an enzyme with another molecule is through a lock-and-key model or induced fit model. In the lock-and-key model, the enzyme has a specific active site that fits the substrate like a key into a lock. The induced fit model suggests that the enzyme undergoes a conformational change to better accommodate the substrate. Both models help visualize the specificity and mechanism of enzyme-substrate interactions.
How has the lock and key theorybeen modified by the inducedfit model?
The induced-fit model builds upon the lock and key theory by emphasizing that both the enzyme and substrate undergo conformational changes upon binding to each other. This model suggests that the enzyme's active site can actually change shape to accommodate the substrate more effectively, resulting in a tighter fit and enhancing catalytic efficiency.
The induced fit model of enzyme action fine tunes the original concept of the lock and key model and modifies it This induced fit model changes the original explanation by hypothesizing that?
The modified lock and key model, now called the induced fit model suggests that enzymes' active sites are modified to fit substrates and then initiate a chemical reaction. Enzymes reorganize protein components to grip substrates at their specific active site, press on the chemical bonds and weaken them, and either form or break chemical bonds, changing the substrate into a product.
What are the two models that illustrate the binding of the substrate to the enzyme?
The two models are the lock-and-key model, where the substrate fits perfectly into the enzyme's active site like a key in a lock, and the induced fit model, where the active site of the enzyme changes its shape slightly to accommodate the substrate upon binding.
