Question

which statement best shows how primary structure relates to protein function? proteins are sensitive to changes in ph changing one amino acid in the protein hemoglobin causes sickle - cell anemia high temperatures cause proteins to denature. the shape and chemistry of an enzymes active site determine its function

Explanation:

The primary structure of a protein is its amino - acid sequence. Sickle - cell anemia is caused by a change in a single amino acid in the hemoglobin protein. This shows how a change in the primary structure can have a significant impact on protein function. The other statements relate to factors like pH, temperature, and enzyme active - site properties rather than primary structure.

Answer:

Changing one amino acid in the protein hemoglobin causes sickle - cell anemia
