How does the lock and key help analogy explain enzymes?
The lock and key analogy describes how enzymes interact with specific substrates. Like a key fitting precisely into a lock, enzymes have a specific active site that binds to a substrate of a particular shape, facilitating the chemical reaction. This specificity ensures that enzymes can catalyze specific reactions efficiently.
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 is used to describe how an enzyme interacts with a specific substrate, much like a key fitting into a lock. This analogy emphasizes the specificity of enzyme-substrate interactions. However, it does not fully capture the dynamic nature of enzyme-substrate binding, as enzymes can change shape to accommodate substrates (induced fit model). Additionally, it does not account for factors like enzyme cooperativity or allosteric regulation.
What are all the enzymes that use the lock and key model?
ALL enzymes use the lock and key model!
What is lock and key?
Lock and Key is one of the theories behind how enzymes fit together with substrates and act as biological catalysts that speed up a reaction in the body. The enzyme usually allows this to happen at much lower temperatures than normal and whithin the range of the animals body. The lock and key refers to the tight specific fitting of the substrate with the enzyme so that specific enzymes can target specific substrates.
Compare enzyme activity with a lock and key?
Lock and key is an analogy of enzyme catalysis in a cellular reaction. The lock and key are compared directly to the substrate and enzyme, because of the high specificity of their physical shape. Enzymes participate in the reaction they catalyze. The reactant molecule (substrate) binds to the enzyme molecule at a particular location called the active site. (this is compared to the lock with keyhole) The highly specific nature of an enzyme is due to very precisely defined arrangement of atoms in the active site(again, this is the lock in the analogy). The substrate molecule must have a matching shape (here is the key) that will fit into the active site. The bond breaking and bond forming processes that transform the substrate into products occur while the substrate is bound to the active site of enzyme. In other words its something like a jigsaw puzzle where the substrate fits into the enzyme. The reaction occurs and the substrate then leaves the enzyme as products. ( Not my work. Found it on Yahoo Answers.....Do not give me credit...Thought I should do this to help people out =] ) Edited answer for readability and clarity - thanks!

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 the structural classification of enzymes?
I believe it is a "Key in a lock" formation
What is considered a model for enzymes actions?
the answer is lock and key model .
How does the lock and key mechanism work?
The lock and key mechanism describes how enzymes interact with specific substrates. Enzymes have active sites that bind to complementary substrates like a key fitting into a lock. This specific binding allows the enzyme to catalyze a chemical reaction with the substrate.
A good analogy for the way in which a neurotransmitter binds to receptor sites is?
a key fitting in the lock of a door
Which substances fit together like a lock and key?
Enzymes and their specific substrates fit together like a lock and key. Enzymes have specific binding sites that perfectly match the shape of their substrates, allowing for efficient catalysis of specific chemical reactions. This lock-and-key model is essential for the specificity and efficiency of enzyme-substrate interactions.
What is needed when your key turns and turns in the door lock without locking. Do I need a new key or new lock?
If the key turns, but the lock doesn't function, then the lock is broken.

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.
