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 the sequence of amino - acids. Sickle - cell anemia is caused by a change in one amino - acid in the protein hemoglobin. This shows how a change in the primary structure (amino - acid sequence) can lead to a change in protein function, as abnormal hemoglobin in sickle - cell anemia causes red blood cells to sickle and impairs their oxygen - carrying function.

Answer:

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