Unit 2 Exploration 1 Lesson 54

Multiple Choice

Explain the significance of the primary structure of proteins in determining their final shape and function.

• The primary structure has no impact on the final shape and function of proteins.

• The primary structure determines the sequence of amino acids, which influences folding and function.

• The primary structure only affects the protein's ability to dissolve in water.

• The primary structure is irrelevant once the protein is synthesized.

Multiple Choice
