on? If proteins could fold only into rigid, inflexible structures, how might this affect the cell's ability to regulate their function? If proteins were inflexible, tertiary structures could not appear, so those proteins could not perform their function. If proteins were inflexible, cell structures could perform normally. If proteins were inflexible, peptide bonds would not be so stable compared to linkages in other types of macromolecules. So those proteins would not be able to perform their function. If proteins were inflexible, those which structure is aff
-In many proteins, especially those involved in cell signaling, their structure is affected by binding to other molecules or ions. Since the Shape of the protein is directly involved in its function, the protein's activity is regulated by controlling how it is folded. If proteins were inflexible, this type of control could not occur.
-Proteins are highly variable in overall shape and chemical properties due to variation in the composition of R-groups and the array of secondary through quaternary structures that are possible. This variation allows them to fulfill many different roles in the cell. Diversity in the shape and reactivity of active sites also makes them effective catalysts.
