____ sequence of amino acids in a protein
8) What happens to a protein when it is denatured?
9) how does denaturation affect the function of a protein ? Why?
10) explain how each causes a protein to denature
a) subjecting the protein to high temperature
b) placing the protein in a strong acid
c) plaing the protein in an organic solvent
