Activation energy is the energy that must be provided to make a reaction take place. The enzyme helps speed up the reaction by lowering the activation energy making the reaction occur at a lower temperature than it would without an enzyme.
So when a substrate binds to the active site of an enzyme, the shape of its molecule is lsighty changed. this makes it easier to change into a product. AS student.
It lowers it.
The substrate is the molecule that binds to the active site of an enzyme. The active site is a region on the enzyme where the substrate binds and undergoes a chemical reaction. The specificity of the active site allows only certain substrates to bind and react with the enzyme.

When a substrate binds to an enzyme, they form an enzyme-substrate complex. This binding lowers the activation energy required for the reaction to occur, making it easier for the reaction to proceed. Once the reaction is complete, the products are released and the enzyme is free to catalyze another reaction.
No, acetyl CoA is not an enzyme. It is a molecule that plays a key role in metabolism by carrying acetyl groups between reactions in cells.
Allosteric inhibition occurs when a molecule binds to a site on an enzyme that is not the active site, causing a change in the enzyme's shape and reducing its activity. Competitive inhibition, on the other hand, happens when a molecule competes with the substrate for the active site of the enzyme, blocking the substrate from binding and inhibiting the enzyme's function.
The site on the surface of an enzyme where a reactant binds is called the active site. This is where the chemical reaction takes place between the enzyme and its substrate. The active site has a specific shape that allows it to bind with the substrate molecule.
Generally in an enzyme-catalyzed reaction, the reactant is called the substrate, which in association with the enzyme forms the product.
The reactant for the enzyme peptidase is a peptide molecule. Peptidase enzymes catalyze the breakdown of peptide bonds within peptides or proteins, resulting in the release of amino acids.
The reactant for lipase is a lipid molecule, such as a triglyceride. Lipase is an enzyme that breaks down lipids into fatty acids and glycerol through a hydrolysis reaction.
If the reactant is affected by an enzyme, it then referred to as a SUBSTRATE.
If a reactant molecule with a different shape than the enzyme comes into contact with the enzyme's active site, it is unlikely to bind effectively. Enzymes have specific active sites that accommodate only particular substrates, a concept known as the "lock and key" model. If the shape does not fit, the molecule will not trigger the catalytic activity of the enzyme, and no reaction will occur. This specificity ensures that enzymes catalyze only the intended biochemical reactions.
The substrate is the molecule that binds to the active site of an enzyme. The active site is a region on the enzyme where the substrate binds and undergoes a chemical reaction. The specificity of the active site allows only certain substrates to bind and react with the enzyme.
substrates
In a typical enzyme reaction, the substrate is the molecule upon which the enzyme acts. It binds to the enzyme's active site, forming an enzyme-substrate complex. This interaction facilitates the conversion of the substrate into products, which are then released, allowing the enzyme to catalyze further reactions.
the region where a reactant binds to an enzyme is known as the active site
If a reactant molecule with a different shape than the enzyme comes into contact with the enzyme's active site, it is unlikely to bind effectively. Enzymes are highly specific, and their active sites are tailored to fit specific substrates, much like a key fits a lock. If the shape does not match, the molecule will not form the necessary interactions to catalyze a reaction, resulting in no enzymatic activity. This specificity is crucial for proper metabolic function and regulation within biological systems.
The reactant for the enzyme aspartase is aspartic acid. It catalyzes the conversion of aspartic acid into fumaric acid.
