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.
What does the lock and key model mean?
The lock and key model is a concept in biochemistry that describes how enzymes and substrates interact. In this analogy, the enzyme is the "lock," and the substrate is the "key" that fits perfectly into the enzyme's active site. This specific fit allows the enzyme to catalyze a reaction, emphasizing the importance of the precise shape and structure of both the enzyme and the substrate for biochemical processes. The model highlights the specificity of enzyme-substrate interactions in biological systems.
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 However this theory is outdated and the inducted fit method is a much better representation.
Which describes a model of a process in which the substrate fits into the active site to form a substrate enzyme compound?
The model you are referring to is the lock-and-key model of enzyme-substrate interaction. This model proposes that enzymes have specific active sites that perfectly fit the substrate, similar to how a lock fits a key. This precise fit allows for the formation of the enzyme-substrate complex and subsequent catalysis of the reaction.

How is a substrate and its enzyme like a lock and key?
A substrate and its enzyme are like a lock and key because they have specific shapes that fit together perfectly. Just like a key must fit exactly into a lock to open it, the substrate must fit into the enzyme's active site for a reaction to occur. This specific interaction ensures that only the correct substrate is acted upon by the enzyme.
What is considered a model for enzyme?
the answer is lock and key model .
In the lock-and-key model of enzyme function shown in Figure 2.2 what is happening in step 1?
In step 1 of the lock-and-key model of enzyme function, the substrate (the key) fits into the enzyme's active site (the lock) with precise specificity. This interaction forms an enzyme-substrate complex, allowing the enzyme to stabilize the transition state and facilitate the chemical reaction. The model emphasizes the complementary shapes of the enzyme and substrate, illustrating how enzymes are selective in their action on specific substrates.
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 best analogy for how an enzyme and its substrate works?
An enzyme and its substrate work like a lock and key. The enzyme (lock) has a specific shape that perfectly fits the substrate (key), allowing them to bind together. This precise interaction facilitates the chemical reaction, much like a key unlocking a door. If the key doesn't fit, the lock won't open, illustrating the specificity of enzyme-substrate interactions.
What is the modification of the lock and key model that suggests the active site of an enzyme?
The modification of the lock and key model that suggests the active site of an enzyme is known as the "induced fit model." This model proposes that while the active site of an enzyme has a specific shape (like a lock), it can undergo conformational changes upon substrate binding (like a key adjusting to fit the lock). This flexibility allows for a more precise interaction between the enzyme and its substrate, enhancing catalytic efficiency. The induced fit model highlights the dynamic nature of enzyme-substrate interactions compared to the rigidity of the original lock and key model.
Why does denaturing by temperature or pH make an enzyme non-functional?
Active site of an enzyme is fixed for particular substrate, or you can understand it better via lock-key theory, in which substrate acts as a lock and active side of the enzyme as a key, and you know well that each lock has a specific key to make it unlock. So if active site of an enzyme is altered due to any reason, it can not be fixed into the its particular substrate, and functioning of an enzyme obliviously requires a substrate.
