Questions and Answers

What temperature is defined as the optimal temperature for enzymes?

  • 100º C
  • 37º C (correct)
  • 0º C
  • 25º C

    • How does a high temperature affect the enzyme's active site?

  • It increases the substrate concentration
  • It enhances the enzyme's activity
  • It causes the enzyme to unfold (correct)
  • It prevents substrate binding

    • What happens to enzyme activity at extreme temperatures?

  • It decreases due to denaturation (correct)
  • It remains constant
  • It reaches maximum efficiency
  • It increases exponentially

    • Why does high temperature cause enzymes to cease functioning?
