What else can I help you with?
Are enzymes permanently change in the chemical reactions they are involved in?
No. That is one of the definitions of an enzyme. It is NOT altered in the reaction.
What chemical reactions within the body sometimes require special proteins called to catalyze the reaction?
The (general) name of proteins that makes chemical reactions inside the body work is 'enzyme'. Enzymes have a 'catalyst' function. There is one for each specific biological reaction.
What is a enzyme controlled reaction?
An enzyme-controlled reaction is a biochemical process in which an enzyme acts as a catalyst to accelerate the rate of a chemical reaction without being consumed in the process. Enzymes lower the activation energy required for the reaction to occur, allowing substrates to convert into products more efficiently. These reactions are highly specific, meaning that each enzyme typically catalyzes only one type of reaction or acts on a specific substrate. Enzyme activity can be influenced by factors such as temperature, pH, and the concentration of substrates or inhibitors.
How do enzymes control the rate of reaction?
Not exactly. An enzyme is a form of catalyst. Organic in nature, they can be astonishingly powerful compared to the inorganic catalysts such as platinum, nickel or water. A catalyst generally speeds up a reaction. The control of reaction speeds in the body usually involves two enzymes, one a catalyst and the other an antagonist which interferes with the function of the first one. Some form of feedback loop finely adjusts the amounts of each of these, and the balance controls the speed of the reaction.
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.
What enzyme speeds up a chemical reaction is known as?
All enzyme's are catalysts for certain chemical reactions. Each enzyme will only work with a certain substrate one analogy being that the enzyme is a key and the substrate is a keyhole, and each enzyme has a unique enzyme.
What do enzymes to do a chemical reaction?
Enzymes are catalysts in a chemical reaction, they are used in chemistry to increase the speed of a specific chemical reaction. A single enzyme will not speed up multiple chemical reactions, usually it is limited to one reactant.
Are enzymes permanently change in the chemical reactions they are involved in?
No. That is one of the definitions of an enzyme. It is NOT altered in the reaction.
How many substrates can an enzyme have?
An enzyme can have multiple substrates, as it can bind to more than one substrate molecule at a time. This binding can occur at the active site of the enzyme, where the substrates interact with the enzyme's catalytic residues to facilitate the chemical reaction. The specificity of the enzyme's active site determines which substrates can bind to the enzyme.

The (general) name of proteins that makes chemical reactions inside the body work is 'enzyme'. Enzymes have a 'catalyst' function. There is one for each specific biological reaction.
What is a specific enzyme?
A specific enzyme is an enzyme that only changes the speed of ONE reaction. (It only acts on one particular substance that happens to be compatible with that enzyme) i.e. if enzyme A is specific to reaction A, it will change the speed of reaction A. However it will have no effect on any other reaction like reaction B or C.
What does a enzyme do in chemical reaction?
An enzyme generally lowers the activation energy necessary for a reaction to proceed. This in turn may cause more of the reactants to go to products.
What part of the brain controls how long it takes to rect?
One of the limiting factors on reaction time is the chemical/electrical synapses.

What is the function of an enzyme?
Enzymes are biological catalysts that speed up chemical reactions in living organisms by lowering the activation energy required for the reaction to occur. They are highly specific and can catalyze a wide range of reactions within cells.
What is the active site of an enzyme?
The most important part of the enzyme- where the chemical reactions happen. Substrates fit into the active site and are broken down or catalysed into end products (this is called the lock and key model).
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.
