Question

Hemoglobin is a protein involved in oxygen transport. Myosin is a protein found in muscles. Which sentence describes these proteins?

O A. They can swap their functions when the body requires it.
O B. They have the same amino acid sequence and are just folded differently.
O C. They can change their structures when the body needs more of a different type of protein.
O D. Their structures are based on the amino acid sequences in their polypeptides​

Answer 1

Hemoglobin and myosin are different proteins that perform different functions in the body. The structures of these proteins are determined by the sequence of amino acids in their polypeptides. Therefore, option D is correct, and options A, B, and C are incorrect.
