It has been observed that neighboring sections of a polypeptide chain can take shape in such a way as to block the access of water to certain areas of the polypeptide surface. This indicates that
A) water bonds to protein surfaces using hydrogen bonding B) different conformations of the same protein may alter the protein's specificity or reactivity C) enzyme active sites do not work properly when exposed to water D) enzyme-substrate interactions depend upon exposure to water only on select areas of tertiary structure. E) the interior of the protein is entirely hydrophobic. |
