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 else can I help you with?
What is the example of induce fit and lock and key theory?
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.
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 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.
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.
What are the theories of development studies?
Some key theories in development studies include modernization theory, dependency theory, and world systems theory. Modernization theory posits that all societies progress through similar stages of development, while dependency theory emphasizes the unequal distribution of power and resources between nations. World systems theory examines how countries are interconnected within a global economic system, with core nations exploiting peripheral nations for resources and labor.
What is the example of induce fit and lock and key theory?
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 is the name of the theory that describes how an enzyme works?
Lock and Key hypothesis
When enzyme fits into substrate at an active site?
lock and key theory
What are the two theories that explain enzyme specificity?
The lock and key theory and the induced fit theory are two theories that explain enzyme specificity. The lock and key theory proposes that the enzyme's active site is already in the correct shape to bind the substrate, like a key fitting into a lock. The induced fit theory suggests that the active site of the enzyme can change its shape slightly to accommodate the substrate, similar to a glove molding around a hand.
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.
Why won't the key come out of the lock?
The key may not come out of the lock due to a misalignment of the key or the lock mechanism, a damaged key or lock, or debris blocking the key's removal.
How can I unlock a bike lock with a key?
To unlock a bike lock with a key, simply insert the key into the lock and turn it in the direction that opens the lock. Make sure to use the correct key that matches the lock.
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.
Why is the key stuck in the lock?
The key may be stuck in the lock due to a misalignment of the key or the lock mechanism, dirt or debris obstructing the keyway, or wear and tear on the key or lock.
What are the Limitations of cardinal utility?
give the limitations of cardinal utility theory
What open a lock?
A key, or a Combonation
How does a lock work?
A key lock works by putting a key in and when you turn the key it pushes a loose round piece which releases the lock.
