In order to do its work, an enzyme must unite - even if ever so briefly - with at least one of the reactants. In most cases, the forces that hold the enzyme and its substrate are noncovalent, an assortment of hydrogen bonds, ionic interactions and hydrophobic interactions.

Michaelis and MENTON have proposed a hypothesis called complex hypothesis the enzyme substrate compex is an intermediate or transiet complex and bonds involved H.bond vaner waals force sometimes 2 substrates can bind to an enzyme molecule and such reaction are callad as BISUBSTRATE REACTION.
What else can I help you with?
Are enzyme able to heat up molecules so that they can react?
No, this is false.
Why do enzymes react?
The molecule that an enzyme react with, works on, is called a substrate. The substrate varies from one enzyme to another. The active site is the 3-D shape on the enzyme where a substrate binds for the reaction to take place.
Is it true that after the product of an enzyme-catalyzed reaction leavesthe active site the enzyme can no longer react with more substrate?
No, after the product of an enzyme-catalyzed reaction leaves the active site, the enzyme can still react with more substrate to continue catalyzing the reaction. The enzyme is not altered or used up in the reaction, so it can continue to bind to and catalyze additional substrate molecules.
Why did the enzyme react to lactose but not to sucrose?
the enzyme is not the right shape for sucrose
What name is given to the molecules made in an enzyme controlled reaction?
The molecules made in an enzyme-controlled reaction are usually referred to as products. These products are the result of the substrate molecules being transformed by the enzyme during the reaction.

What enzyme is responsible for cutting DNA molecules?
The enzyme responsible for cutting DNA molecules is called a restriction enzyme.
IS FAT A HORMONE OR ENZYME?
No it is not a hormone or an enzyme. It is a type of molecules
How does the allosteric enzyme curve illustrate the relationship between enzyme activity and the binding of regulatory molecules?
The allosteric enzyme curve shows how enzyme activity changes when regulatory molecules bind to the enzyme. This curve demonstrates that the binding of regulatory molecules can either increase or decrease enzyme activity, depending on the specific enzyme and regulatory molecule involved.
What is meant by the enzyme specificity?
Enzymes work on one substrate specifically. This is why there is millions of different types of enzymes to interact with all the molecules they need to metabolically and chemically react with.
Why did the enzyme react to lactose but not to sucrose?
the enzyme is not the right shape for sucrose
Does making an enzyme more acidic help it react?
Depends on the enzyme. Acid activity around the enzyme is the number of protons around the enzyme, which then warps and changes the electrostatic field in localized positions of the enzyme. Think of the enzyme as weirdly shaped glove with a crazy number of fingers, trying to grab specific reactant molecules and hold them in arrangements where they react with each other. The changes in electric fields cause by the acid/base balance moves the glove's "fingers" to either work better or worse in grabbing and aligning the molecules to be reacted. While most natural enzymes work in acid systems, such as digestive enzymes, there are many enzymes that need alkaline conditions to function best.
What name is given to the molecules made in an enzyme controlled reaction?
The molecules made in an enzyme-controlled reaction are usually referred to as products. These products are the result of the substrate molecules being transformed by the enzyme during the reaction.
What happens when activation energy is in presence of an enzyme?
When activation energy is in the presence of an enzyme, the enzyme can lower the activation energy barrier required for a chemical reaction to occur. This allows the reaction to proceed at a faster rate and with lower energy input. The enzyme does this by stabilizing the transition state of the reaction, making it easier for the substrate molecules to react.
The number of molecules with which an enzyme reacts is the?
The number of molecules with which an enzyme reacts is typically one or more substrate molecules. Enzymes bind to their substrates at their active sites to catalyze chemical reactions. The number of substrate molecules that can interact with an enzyme at a given time depends on factors like enzyme concentration, substrate concentration, and the kinetics of the enzyme-substrate complex formation.
