What will be the effect on protein function if each polypeptide adopted only a single, inflexible shape based on its primary structure.
~The protein ability to catalyze would be
impaired. The tertiary structure could not appear, so those proteins
could not perform their function.
~The ability to regulate protein activity would be impaired. The peptide bonds would not be so stable compared
to linkages in other types of macromolecules, so those proteins could not perform their function.
~The ability to regulate protein activity would be impaired. The proteins would be either permanently active or
inactive, depending on how they are folded.
~The proteins would perform their functions normally.
