Question

a drastic conformational change in a protein in response to extreme heat or ph is called __________. multiple choice contamination denaturation saturation sedimentation deconformation

Explanation:

In biology, when a protein undergoes a drastic conformational change due to extreme heat or pH, it is called denaturation. This disrupts the protein's structure and function. The other terms - contamination refers to foreign substances, saturation is related to binding capacity, sedimentation is about particles settling, and deconformation is not a standard term for this phenomenon.

Answer:

B. denaturation
