The lock and key model, though popular, is outdated and not entirely accurate. Regardless, it was used because it provides a simple visual analogy to imagine the enzyme (the enzyme, or key, simply inserts itself into the lock, the molecule to be broken down by the enzyme [known as a substrate]). The more accurate model is now the "Induced fit model", because enyzmes and substrates (the chemicals they act upon) are not naturally able to fit into each other. Instead, each substance changes its shape a little to accomodate the other.

What is considered a model for enzyme?
the answer is lock and key model .
What are all the enzymes that use the lock and key model?
ALL enzymes use the lock and key 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.
What type of model does an enzyme work like?
enzymes work on lock and key model and induced fit model.
Which describes a model of a process in which the substrate fits into the active site to form a substrate enzyme compound?
lock-and-key model
What provides the best model to illustrate the way an enzyme interacts with a substrate molecule?
lock and key
What is the lock-and-key principle of enzyme action?
The lock is the enzyme and it's active site is where you put the key in. The key is like the substrate that comes and binds to the active site, or the key that fits into the lock.
What effect does the lock and key process have on the enzyme structure?
Easily Explained thusly: When the key is in the lock the Enzyme has one Structure, and when the key is not in the lock the Enzyme has another Structure. Note that the presence of a key may either activate or deactivate an Enzyme, depending upon the conditions.
What is the model of enzyme activity?
In a model of enzyme action, the enzyme can attach only to a substrate (reactant) with a specific shape. The enzyme then changes and reduces the activation energy of the reaction so reactants can become products. The enzyme is unchanged and is available to be used again.
What is the term for an enzyme catalyzes only one type of reaction?
It is called a lock and key mechanism.Actually is more than one word. It is called a lock and key mechanism. Only one key can unlock one lock.
In the lock and key method which is the lock?
The Key is the substrate while the key is the enzyme. Just finished learning this :)
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.
