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.

Which feature of an enzyme determines the chemical process it aids?
The feature of an enzyme that determines its chemical process it aids is it's shape. This can be compared to a lock and key. Where an enzyme, as the key, must have a certain structure or multi-dimensional shape that matches a specific section of the substrate, the compound or substance that undergoes the change.
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
Why do enzymes have an active site?
The structure of an enzymes and its active site determine which substrates will work for the enzyme. This is called the lock and key method. The active site is the lock and the substrate is the key.
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 However this theory is outdated and the inducted fit method is a much better representation.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 part of the enzyme does the substrate lock on to?
Today
What is considered a model for enzyme?
the answer is lock and key model .
How is a substrate and its enzyme like a lock and key?
An enzyme is shaped so that a specific substrate can attatch to it. A lock and a key function in a similar way. Each lock is shaped so that only a certain key can open it.
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 determines an enzyme's functions and how many functions does one enzyme have?
An enzyme has only one substrate that it works with so it has only one function. This is called a lock and key mechanism. Other things can affect the enzyme such as temperature, pH level and levels of either the substrate or the products. High temperature can denature the enzyme (they are proteins). They can not fit the lock (substrate).

Why do denatured enzymes become disfunctional?
An enzyme's ability to function comes from its shape, which is a result of the folding of the amino acid chain that it's made of. Enzymes act on their substrates (just a fancy word for whatever molecule or chemical or anything that an enzyme acts on) on a certain part of the enzyme called the active site. This can be modeled by an example such as a lock and a key. The lock would be the enzyme, and the key the substrate. It's a very specific fit. When an enzyme becomes denatured, it starts to unfold, which changes its shape. Changing the shape of the active site, means that the substrate no longer fits, just as the key would no longer fit if you heated the lock until it melted. Since the substrate can no longer bind to the enzyme's active site, the enzyme is no longer effective.
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.
