Answer
D) all of the above are correct
agents that disrupt the structure thereby denaturing the protein:
1) changes in pH (alters electrostatic interactions between charged amino acids)
2) changes in salt concentration (does the same)
3) changes in temperature (higher temperatures reduce the strength of hydrogen bonds)
