Many times enzymes have multiple active sites that allow for many simultaneous reactions. For example, it's possible to have a fourth of the number of enzymes as substrate molecules, but the enzyme may have four active sites, resulting in one active site per substrate molecule.
What else can I help you with?
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.
Which characteristics of an enzyme?
An enzyme is a protein, so is in its most basic form, a string of amino acids. However, hydrogen bonds between molecules in the string make the chain fold into a large, bundled shape that will have an 'active site' that will only allow bonding one specific substrate.
Why is catalyst effective in small amounts?
Catalysts are effective in small amounts because they facilitate chemical reactions by lowering the activation energy required for the reaction to occur, allowing reactants to convert to products more easily. They are not consumed in the reaction, meaning a single catalyst molecule can participate in multiple reaction cycles. This efficiency allows a small quantity of catalyst to influence a large number of reactant molecules, enhancing the overall reaction rate without the need for large amounts of the catalyst itself.
How does an enzyme catalyze the synthesis of a large molecule from two smaller molecules?
An enzyme catalyzes the synthesis of a large molecule from two smaller molecules by lowering the activation energy required for the reaction to occur. It binds to the substrates, bringing them into close proximity and orienting them in a way that facilitates the formation of new bonds. This process often involves the formation of a transient enzyme-substrate complex, allowing for the efficient conversion of substrates into the product. Ultimately, the enzyme is released unchanged, ready to catalyze additional reactions.
Large protein molecule that speeds up a chemical reaction?
An enzyme is a large protein molecule that functions to speed up chemical reactions by lowering the activation energy required for the reaction to occur. Enzymes are highly specific to the reactions they catalyze and can be reused multiple times.
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.
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 enzyme halal?
All intoxicants which affect the senses and result in the loss of common sense are Haram/unlawful in Islam, be they in small quantity or in large quantity.

What does small amount of an enzyme can cause the reaction of large quantities of substrate mean?
This statement means that enzymes are catalysts that can speed up chemical reactions, allowing a small amount of enzyme to effectively convert a large amount of substrate into products. Enzymes achieve this by lowering the activation energy required for the reaction to occur, enabling more substrates to be converted in a shorter amount of time.
Should A large quantity of books have a plural predicate?
No. The subject a large quantity of books is used in the singular and all verbs should be conjugated accordingly, e.g. A large quantity of books was destroyed in the fire; A large quantity of books was donated to the orphange.
Which country produce large quantity of Sternum?
The Western countries produce the large quantity of Sternum.
What are two ways you can increase the rate of a chemical reaction?
The most effective way to increase the rate of reaction is to increase the temperature. This is effective up to a certain temperature (depending on the specific reaction and enzyme). Above that point the reaction may slow down (drastically) or stop entirely. Note that enzymes speed up a chemical reaction by physically binding with a substrate (or substrates) and causing the appropriate change (breaking apart a large molecule into two or more pieces, combining two substrates into one molecule, etc.) A substrate is a material (chemical, element, compound, whatever) that is undergoing a reaction. It is changed by the reaction. If the materials that are reacting are heated past an enzyme's tolerance, the enzyme undergoes what is known as "denaturation." This means that the molecule physically alters, losing the specific shape that allows it to function as an enzyme. As a reminder, heat is defined as random kinetic energy. That is, heat causes atoms, molecules, proteins, etc. to move around in a random fashion. Heat can speed up a reaction because it moves around the substrate and enzyme molecules faster, allowing them to "bump into" each other more often. By the same token, this random movement will, if great enough, shake up a molecule so much that molecule falls apart or alters in some way. High heat denatures the molecule. Another technique is to increase the amount of substrate and/or enzyme. Increasing the substrate or enzyme increases the rate of reaction because the two materials will bump into each other more quickly and frequently.
