Question

What is a prosthetic group? Select the single best answer. a nonprotein group attached to a protein, but not required in order for the protein to function a second protein group required in order for a protein to function an enzyme group required in order for a protein to function an amino acid group required in order for a protein to function an amino acid group attached to a protein, but not required in order for the protein to function a second protein group attached to a protein, but not required in order for the protein to function a nonprotein group required in order for a protein to function

Answer 1

The last option " A non- protein group required in order for a protein to function" is the correct answer.

Prosthetic group is a non-protein component of a conjugated protein or the co-factor of an enzyme. So all options can be eliminated except first and last one.

They are specific non-polypeptide required for the biological function of some protein. So first option is also eliminated.

The prosthetic group may be organic, inorganic but not composed of amino acids.

Heme is an example which is a prosthetic group present in cytochrome oxidase.
