On each surface of enzyme there are detachable cofactor (non-protein portin of enzyme) called activators. Activators are metal ions.
Enzymes are proteins and literally fold into a specific 3d structure, to make space for an active site (also called activators). Active site has a shape that fits with specific substrate molecules.
The enzyme and substrate form a temporary enzyme-substrate complex.
Enzymes are flexible structures.
When enzyme and substrate bind together, the shape of enzyme molecule undergoes slight change.
This produces strain in chemical bond in the substrate molecules and as a result these bonds break and bonds are formed. These stresses encourage a link between two substrstes leading to the formation of a different molecule.
As the result of the chemicl interactions within the active sites a new chemical compound is formed. The new chemical compound is called product.
This product is released from the active site, the enzyme assumes its orignal shape and is free to work again.

Difference between activator and prosthetic groups?
Prosthetic groups can be as simple as a single metal ion bound into the enzyme's structure, or may be a more complicated organic molecule (which might also contain a metal ion). it is permanently bonded to enzyme. Activator is only metal ion that is detachable. source:chemguide.co.uk Stuffidious.com
What is a metal ion?
A metal ion is an atom of a metal element that has lost one or more electrons, resulting in a positive charge. Metal ions are commonly found in chemical reactions and biological processes due to their ability to participate in various bonding interactions. They are important for the structure and function of many molecules and compounds.
What compound is composed of a metal plus polyatomic ion?
An example of a compound composed of a metal and a polyatomic ion is magnesium sulfate (MgSO4). In this compound, magnesium is the metal, and the sulfate ion (SO4) is the polyatomic ion.
Is iodine a metal or non-metal and what ion does it form?
Iodine is a nonmetal and it forms the iodide ion, I-.
What is the metal ion of potassium nitrate?

Which term refers to a macromolecule that attaches to an enzyme and plays a helper role in catalysis?
A cofactor refers to a macromolecule that attaches to an enzyme to assist in catalysis. This can be a metal ion or a coenzyme.

Are there any metal elements in salt?
All inorganic salts are composed of a metal ion (or an ammonium ion) and an acid radical ion. Table salt for example is composed of a sodium ion and a chlorine ion (the radical ion of hydrochloric acid).Organic salts (called esters) may or may not contain a metal ion. Organic salts that do not contain a metal ion, its role is taken by an alkaloid radical ion.
What is metalloprotein?
Metalloprotein are those which contain metal ions such as iron, cobalt, nickel etc., these proteins are usually enzymes and co factors for enzymes and comes under the category of conjugated proteins in which the non-protein part (metal ion) is called as prosthetic group or conjugatin group.
What is a cofactor?
A cofactor is a non-protein chemical compound or metallic ion that is required for an enzyme's activity. It helps enzymes to catalyze reactions by assisting in the transfer of functional groups during the reaction process.
What small organic molecule is required for the functioning of an enzyme?
coenzyme
What chemical reactions take place when a biological catalyst combines with a reactant to form an unstable intermediate?
When a biological catalyst combines with a reactant to form an unstable intermediate, the catalyst facilitates the breaking and forming of chemical bonds in the reactant molecule through mechanisms such as acid-base catalysis, covalent catalysis, or metal ion catalysis. This leads to the formation of a transition state that is energetically favorable for the reaction to proceed, ultimately resulting in the formation of products and regeneration of the catalyst.
Is edta an enzyme?
No, EDTA (ethylenediaminetetraacetic acid) is a chelating agent, not an enzyme. EDTA binds metal ions and is commonly used in laboratories to prevent metal ion contamination in reactions or to chelate metal ions in solutions.
Is an oxyanion named based on the amount of a metal in the ion?
No, the name of an oxyanion is not based on the amount of a metal in the ion. The name of an oxyanion is determined by the oxidation state of the element and the number of oxygen atoms in the ion. The metal in the ion may play a role in determining the charge or oxidation state of the element, but it does not directly determine the name of the oxyanion.

sodiumtetrahydoxylaluminate(Na(alOH4))
