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.

An activator is a molecule that binds to an enzyme and enhances its catalytic activity, while a prosthetic group is a non-protein molecule that is permanently attached to an enzyme and is required for its activity. Prosthetic groups usually participate in the catalytic reaction, while activators simply increase the enzyme's efficiency.

What is the difference between coenzyme and prosthetic group?
A coenzyme is a non-protein compound that binds to an enzyme to help it function properly, while a prosthetic group is a non-protein component that is permanently attached to an enzyme and is essential for its activity. In other words, coenzymes are temporary helpers, while prosthetic groups are permanent additions to the enzyme structure.
Which of the not a prosthetic group of nitrate reductase?
Nitrate reductase does not contain the prosthetic group heme. Instead, it typically contains molybdenum cofactor (Moco) and heme iron-sulfur center as prosthetic groups.
What is a prosthetic group?
A prosthetic group is a non-protein compound that is permanently attached to a protein, essential for the protein's function. It may participate in the catalytic activity of the protein or aid in binding other molecules. Examples include heme in hemoglobin and biotin in enzymes.
Prosthetic group of enzyme is organic or inorganic?
A prosthetic group of an enzyme can be either organic or inorganic. Organic prosthetic groups are typically large molecules, such as coenzymes, that are often derived from vitamins. In contrast, inorganic prosthetic groups are usually metal ions that are required for catalytic activity, such as iron in heme groups.
What is conjugate protein?
Conjugated proteins are proteins that are covalently linked to other biomolecules such as lipids, carbohydrates, or prosthetic groups. These modifications can alter the structure, function, and localization of the protein in the cell.
What is the difference in co enzyme and prosthetic group?
A coenzyme is a small, organic molecule that helps enzymes function by carrying chemical groups between enzymes, while a prosthetic group is a non-protein molecule covalently bound to a protein and is essential for its biological activity. In simpler terms, coenzymes are temporary helpers, while prosthetic groups are permanent attachments to proteins.

In other words, coenzymes are temporary helpers, while prosthetic groups are permanent additions to the enzyme structure.
What is prosthetic group?
A prosthetic group is an area of a protein or protein complex that can be reduced and oxidized. Flavoproteins and Cytochromes are two examples of complexes with prosthetic groups.
Is a zinc atom prosthetic group?
No, a single zinc atom is not considered a prosthetic group. Prosthetic groups are non-protein components that are permanently attached to a protein and are essential for its function. Zinc ions can act as cofactors, which are required in catalyzing enzyme reactions, but they are not considered prosthetic groups on their own.
Which of the not a prosthetic group of nitrate reductase?
Nitrate reductase does not contain the prosthetic group heme. Instead, it typically contains molybdenum cofactor (Moco) and heme iron-sulfur center as prosthetic groups.
What is the Difference between interest groups and pressure groups?
Pressure groups are the organisations or the groups that attempt to influence government policies.
Within collagen structure re there any prosthetic groups?
No, collagen does not contain any prosthetic groups. It is a fibrous structural protein composed of three intertwining polypeptide chains called alpha helices that form the typical triple helical structure.
What is the difference between formal groups and informal groups?
Formal groups have a stated , common purpose . They generally have a group leader , or each member takes a turn at leading the group.
What is the difference between lobbyist and interest groups?
To eat banana pudding.
What is the primary difference between global and universal groups?
Universal groups add more data to the global catalog.
Can vitamins act as prosthetic group in enzymes?
Yes! The umbrella term for coenzymes and prosthetic groups is 'cofactor' - though many internet and book sources interchange the terms. If someone says 'cofactor' they could mean either 'prosthetic group' OR 'coenzyme'. One example of a vitamin prosthetic group is vitamin B12, biotin. Like all prosthetic groups, this tightly bound molecule cannot leave its enzyme, or the enzyme shall not be able to function properly. Coenzymes on the other hand, CAN leave the enzyme it works with; it is a free molecule. Hope this helps! SOURCE: Vigourous scientific literature searches for my degree.
