What happens to enzyme activity when temperature rises significantly above its optimum?

  • AActivity slows gradually then speeds up
  • BActivity remains constant
  • CEnzyme is denatured and loses activity
  • DEnzyme replicates to compensate
Permalink
Correct Answer: Option C — Enzyme is denatured and loses activity
Explanation: When temperature rises significantly above the optimum the enzyme is denatured meaning the active site changes shape so the substrate can no longer bind and activity is permanently lost.
