The porphyrin prosthetic group is held into the interior of globin molecules by covalent bonds to specific amino acid residues.Answers: TrueFalse

Answering the Question

The statement in question pertains to the structure of globin molecules and the interaction between the porphyrin prosthetic group and amino acid residues within these molecules.

In reality, the porphyrin group, such as heme in hemoglobin, is typically held in place by non-covalent interactions with the surrounding amino acids rather than covalent bonds. While there may be some instances where specific interactions occur that could resemble covalent binding, these are not the primary mechanisms through which the prosthetic group is retained.

Therefore, the correct answer to the statement is:

False.

The porphyrin prosthetic group is primarily held in globin molecules by non-covalent interactions, not by covalent bonds to specific amino acid residues.
