Upon increasing the temperature the shape of enzyme's active site?

Correct answer: B. Denatures

  • A. Remains same
  • B. Denatures
  • C. Adopts a geometric conformation
  • D. Dissolves

Explanation

Upon increasing the temperature, the shape of an enzyme's active site may change. Enzymes have an optimal temperature at which they function most effectively. If the temperature becomes too high, the enzyme may undergo denaturation, where it loses its native structure irreversibly. Denaturation leads to a loss of enzyme activity as the active site is no longer able to bind with the substrate.

About Enzymes

Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
