How are the ''lock and key'' and ''induced fit'' models similar?
bontot
What happens to the enzyme after it separates from the new molecule?
It returns to its original shape, and is reused. Look up the 'lock and key' and 'induced fit' models.
Explain why a lock and key are used to descrive the way an enzyme works describe any ways in which the analogy is NOT perfect?
The Lock and Key analogy states that enzymes are highly specialized and will only fit certain substrates. However, this is incorrect because it is actually an induced fit.
What is the active site on a substrate?
Enzymes and substrates will bind together to catalyse chemical reactions. The spot on the enzyme where the substrate will bind is called the active site of the enzyme. The enzyme and the substrate are usually a pretty close fit, hence the naming of the induced fit model.
As an enzyme fits into a substrate at the active site it undergoes a slight change in order to fit into the substrate. this process is defined by a concept called?
This concept is called an induced fit.

How the lock and key model and the induced fit model differ?
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.
What type of model does an enzyme work like?
enzymes work on lock and key model and induced fit model.
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
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.
What is the Mode of action of enzymes in terms of substrate complex?
These are the modes: 1. Lock and Key hypothesis 2. Induced Fit Hypothesis
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 happens to the enzyme after it separates from the new molecule?
It returns to its original shape, and is reused. Look up the 'lock and key' and 'induced fit' models.
This is a modification of the lock and key model that suggests the active site of an enzyme is continually reshaped by interactions with the substrate until the substrate is completely bound and the c?
induced fit
Explain why a lock and key are used to descrive the way an enzyme works describe any ways in which the analogy is NOT perfect?
The Lock and Key analogy states that enzymes are highly specialized and will only fit certain substrates. However, this is incorrect because it is actually an induced fit.
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.
