The text states that "A protein's specific structure determines how it works." Given this, what would be the most likely consequence if the unique three-dimensional shape of a functional protein were significantly altered?

  • A: The protein would gain new, enhanced functions.
  • B: The protein's amino acid sequence would change to compensate.
  • C: The protein would likely lose its specific function or ability to recognize other molecules.
  • D: The protein would spontaneously refold into its original structure.

Explanation

The text emphasizes that "A protein's specific structure determines how it works" and that its function depends on its "ability to recognize and bind to some other molecule." Therefore, a significant alteration to its unique three-dimensional shape would lead to a loss of its specific function or binding ability.
