What is non-competitive enzyme inhibitor?
Competitive inhibition is where a inhibitor has a structural similarities of a substrate. Due this the inhibitor binds to the active site of the enzyme,where normally substrate binds. This binding of the inhibitor to the enzyme forms a EI complex instead of ES complex and thus inhibiting the catalytic activity of an enzyme. Non competitive inhibition is when inhibitor possessing same structure of substrate binds to the site other than the active site of an enzyme. The substrate binds to the active site of an enzyme. This binding of the inhibitor to the site other than an active site disturbs the normal structure of an enzyme. Thereby, lowering the catalytic activity of an enzyme.
What does a enzyme-substrate complex do?
An enzyme-substrate complex is formed when a subtrate molecule binds with the active site of an enzyme that is of similar shape and size. The active site of the enzyme will alter slightly to combine with the substrate molecule. This will put an strain on a particular bond of the substrate molecule, which will lower the activation energy for the reaction as the bond will break more readily. The substrate is then catalysed.
What is an active site and where is it located?
A region on an enzyme that binds to a protein or other substance during a reaction
What is the role of enzymes in biological systems?
Enzymes are regulated with the use of Competitive Inhibitors and Noncompetitive Inhibitors. Basicly every enzyme has an active site where the substrate binds to and what an the first kind of inhibtor does is that it blocks the substrate from joining with the enzyme by attaching to the enzyme's active site. The other kind of inhibitor joins with the enzyme at another place not the active site. This makes the enzyme change shape so it cannot fit the substrate or it somehow makes the enzyme unable to catalize the reaction.~Draco
Is Enzyme structure is important because the enzymes shape allows only certain substrates to bind to the enzyme?
Yes, enzyme structure is important because the active site of an enzyme is specifically shaped to bind to the substrate. This specificity allows only certain substrates to fit into the active site and form an enzyme-substrate complex. The binding of the substrate to the enzyme is crucial for catalyzing the chemical reaction that the enzyme facilitates.
The specificity of an enzyme is due to its active siteThe active site is a shape only a certain?
An enzyme's active site will bind with only a specific substrate. Any other kind of substrate will be rejected by the active site.

What is the definition of enzyme specificity?
each enzyme has a specific substrate to which it binds through a definite active site and any other enzyme can not bind to it

How does an enzyme recognize its substrate?
On one part of an enzyme is an active site (which is what the substrate binds to) that is shaped a certain way, say a triangle. A substrate that's in the shape of a square won't fit onto the triangle/the enzyme - but a substrate that has an indent in the shape of a triangle will. The way an enzyme recognizes its substrate is if it can attach itself to the enzyme's active site.
Why are enzymes three dimensional shape so important?
An enzyme's three dimension shape is important to the binding that occurs between the enzyme itself and its specific substrate, forming the enzyme-substrate complex. In order for the enzyme to create a reaction it is important that the shape of the enzyme binds the substrate to the active site where the chemical reaction occurs. One other thing to consider is the shape that the enzyme takes that allows only its specific substrate to bind and not any other molecule.
Is Enzyme structure is important because the enzymes shape allows only certain substrates to bind to the enzyme?
Yes, enzyme structure is important because the active site of an enzyme is specifically shaped to bind to the substrate. This specificity allows only certain substrates to fit into the active site and form an enzyme-substrate complex. The binding of the substrate to the enzyme is crucial for catalyzing the chemical reaction that the enzyme facilitates.
How can induced fit influence the specificity of an enzyme?
Induced fit: is a more recent theory which suggests that the substrate attaches to the enzyme in a relatively accurate fit, then the enzyme moulds around it, then continues the chemically complex reaction. Lock and Key Mechanism: As obvious as the name states, the lock and key model is simply the substrate fitting acutely into the enzyme with no adjustments required to the enzyme. K.G. ;)
Inhibitors of enzymes-catalyzed reactions act by?
Different Enzymes inhibit in different ways. Some are structural analogue of substrate and they compete the substrate in binding to the enzyme. Some inhibitors bind in the active site and prevent the binding of the enzyme. Some enzymes doesn't bind the active site but they change the active site properties that prevent the efficient binding of the substrate. some time substrate in large quantity may inhibit the enzyme, while other times the product formed may do so.
The particular region of an enzyme molecule that combines with the substrate it acts upon is called what?
The area where a molecule other than substrate can attach is called the allosteric site.
