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.

What are the limitations of the lock and key theory?
The lock and key theory of enzyme-substrate binding does not account for the induced fit model, where the enzyme and substrate can undergo conformational changes to better fit each other. It also does not explain the binding of substrates that are larger than the active site or the ability of enzymes to catalyze multiple types of reactions.
What is the induced fit theory?
The induced fit theory proposes that the active site of an enzyme changes its shape upon binding with the substrate. This change is induced by the interaction with the substrate, leading to a more precise fit and optimal conditions for catalysis to occur. This theory suggests that the binding of a substrate to an enzyme is a dynamic process rather than a static lock-and-key model.
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.
What is the definition of path-goal theory?
Path-goal theory is a leadership theory that suggests a leader's effectiveness is determined by how well they help their followers achieve their goals by clarifying the path forward, removing obstacles, and providing necessary support and rewards. It focuses on how leaders can motivate followers to reach their objectives by adapting their leadership style to the needs and characteristics of their team.
What are the strengths and limitations of the situational theory?
Strengths of situational theory include its focus on adapting leadership style to different situations, promoting flexibility and effectiveness. Limitations include the complexity of identifying and interpreting situational factors, and the challenge of constantly adjusting leadership approach to fit changing circumstances.
Why is the Induced fit model better than the lock and key model?
induce fit model is better because it causes a change in the enzyme active sit and allows the substrate to fit in
Which statement describes the currently accepted theory of how an enzyme and its substrate fit together?
There is an enzyme explanation whose specificity states that an enzyme and its substrate possess specific complementary geometric shapes that fit exactly into one another. This is the lock and key explanation.Ê
To fit or lock together?
Interlock
What is the meaning of the concession theory in corporate theory?
Under the thinking of the concession theory, the ability to form a company is nothing more than a concession granted by the State. As such, the State should be able to intervene in anyway it sees fit. An example of this theory in practice is in Germany.
Lock and key method?
In biology the lock and key method states that an enzyme and it's substrate are complementary and only the correct substrate can bind with the enzyme, this is due to the folding in the protein structure. However this theory is outdated and the inducted fit method is a much better representation.
What is geographic fit evidence of?
The continental drift theory and the plate tectonic theory
Which theory makes the use of Jigsaw fit in its support?
Continental Drift Theory
What is the lock and key analogy for enzymes?
The Lock and Key Analogy of Enzymes and Substrates:Enzymes act as a catalyst in a given chemical reaction (for example, lactase allows lactose to break down into Glucose and Galactose); enzymes lower the amount of energy required to make a reaction occur. There is a key concept to this theory: Enzymes are designed work for only one reaction; there is only one key that fits the lock perfectly.Without enzymes, our bodies wouldn't be able to handle the amount of heat the reactions that occur inside if there weren't any enzymes (or the reactions just wouldn't occur!In the Lock and Key Analogy, the substrate (Lactose in the example) is the "key". The key must fit perfectly into the active site that is on the enzyme, or the "key hole in the lock (Lactase is the Lock in the example). The substrate will then break down into its products (which in the example would be the Glucose and Galactose).This can happen in different ways: 1) two (or more) substrates can bind onto the same active and combine to form one product; 2) one substrate can bind onto an active site and break down to form two (or more) products......Here is a picture of what the Lock and Key Theory looks like:http://i677.photobucket.com/albums/vv133/erica46829/LockandKeyTheory.jpg

What is a general statement about how some parts of the world fit together and how they work?
A theory.
What is key and lock theory?
It is when the enzyme (lock) fits exactly into the substrate (key) forming an enzyme substrate complex. It refers to enzymes and their substrates. The enzyme has an active site (lock) where the substrate that is complemetary fits in (key). Only substrates that fit perfectly into the enzymes active site will active the particular reaction, just like only 1 specific key will open a door.
When would scientists need to change a theory?
Scientists had made observations that did not fit exactly with Dalton's theory. Scientists changed the atomic theory to include this new knowledge. While the modern atomic theory is based on Dalton's theory, it is also very different.
