What else can I help you with?
The region of the enzyme that is complimentary in shape and charge to the substrate is known as the?
Active site .
Why will only certain substrate molecules fit into the active site?
It will only bind with the enzymes active site of the shapes are complimentary and enzymes are very specific
Is Enzyme structure is important because the enzymes shape allows only certain substrates to bind to the enzyme?
Yes, the stucture of an enzyme's active site (which binds to substrates) and other areas that bind to cofactores are important. Only certain substrates will link to it depending on the shape, eletrostatic interactions and hydrophobicity of an active site.
What inhibitor has a structure similar to the substrate?
Competitive inhibitors have a structure similar to the substrate, allowing them to bind to the active site of the enzyme and block the substrate from binding. This competition for the active site reduces the enzyme's catalytic activity by preventing the substrate from binding and undergoing a reaction.
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.
The region of the enzyme that is complimentary in shape and charge to the substrate is known as the?
Active site .
How are the different types of inhibitors different?
Competitive inhibitors bind to the active site of an enzyme, preventing the substrate from binding. Noncompetitive inhibitors bind to a site other than the active site, changing the shape of the enzyme and preventing substrate binding. Uncompetitive inhibitors bind only to the enzyme-substrate complex, preventing catalysis.
What is it called when and enzyme and substrate come together?
When an enzyme and substrate come together, it is called the enzyme-substrate complex. This complex is a temporary intermediate state in which the enzyme binds to the substrate to catalyze a chemical reaction.

Substrate molecules bind to enzymes where?
The bind in the active site.
How do allosteric regulation and competitive inhibition differ in their mechanisms of enzyme regulation?
Allosteric regulation involves a molecule binding to a site on the enzyme that is not the active site, causing a change in the enzyme's shape and activity. Competitive inhibition involves a molecule binding to the active site of the enzyme, blocking substrate binding and enzyme activity.
What unlocks the active site of an actin molecule?
The binding of ATP to actin causes a conformational change that exposes the active site for myosin binding. This allows for the formation of cross-bridges between actin and myosin during muscle contraction.
What is a molecule occupying the active site of an enzyme so that there can be no normal enzyme-substrate complex formed called?
It is called a competitive inhibitor. Competitive inhibitors bind to the active site of an enzyme, preventing the substrate from binding and inhibiting the enzyme's activity. This type of inhibition can be overcome by increasing the substrate concentration.
State the function of polar regions of amino acids on the active site of the enzyme?
The function of polar regions of amino acids on the active site of the enzyme is that it allows the reaction to take place more easily. The active site is the place where the actual chemical reaction takes place.
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.
When a substrate fits into an active site of an enzyme what is formed?
When a substrate fits into the active site of an enzyme, an enzyme-substrate complex is formed. This complex allows for the enzyme to catalyze a specific chemical reaction on the substrate.
