AA protein that transports a molecule
BA molecule bound to a protein to help it work
CA membrane channel that admits ions
DA sugar attached to a nucleotide base
Answer & Solution
Correct answer: B. A molecule bound to a protein to help it work
1. A prosthetic group is a molecule bound to a protein that facilitates the function of that protein.
2. Prosthetic groups are organic or inorganic non-peptide molecules, so they are not proteins themselves.
3. They include co-enzymes, which are the prosthetic groups of enzymes.
4. Flavin mononucleotide in the first complex is one example of such a group.
