Question

what determines a proteins function?
the percentage of hydrophilic amino acids in the protein
the location of its gene on the chromosome
the three - dimensional shape of the folded protein
the sequence of amino acids
the number of amino acids linked together

Explanation:

The function of a protein is determined by its three - dimensional shape which is formed by the folding of the polypeptide chain. This folding is a result of the sequence of amino acids in the protein. The sequence of amino acids determines how the protein will fold into its specific 3 - D structure, which in turn dictates its function. The percentage of hydrophilic amino acids, gene location on chromosome, and number of amino acids linked together are not the direct determinants of a protein's function compared to the sequence and resulting 3 - D shape.

Answer:

C. the three - dimensional shape of the folded protein, D. the sequence of amino acids
