Which of the following is the strongest evidence that protein structure and function are correlated?
A) Proteins function best at certain temperatures.
B) Proteins have four distinct levels of structure and many functions.
C) Enzymes tend to be globular in shape.
D) Denatured (unfolded) proteins do not function normally.

The fact that denatured proteins, which have lost their native structure and shape, also lose their function is the strongest evidence for the correlation between protein structure and function. This suggests that the specific protein structure is required for the proper function of the protein. The other answer choices describe general features of proteins but do not provide direct evidence for the correlation between structure and function.
