Questions and Answers

What is a characteristic of enzymes that exhibit cooperativity?

  • They have a sigmoidal curve for reaction velocity vs. substrate concentration (correct)
  • They follow Michaelis-Menten kinetics
  • They only bind to one substrate molecule at a time
  • They have a hyperbolic curve for reaction velocity vs. substrate concentration

    • What is the term for the effect of a molecule that binds to an enzyme at a site other than the active site?

  • Heterotropic effect
  • Substrate effect
  • Cooperative effect
  • Allosteric effect (correct)

    • What is the purpose of feedback inhibition in a metabolic pathway?

  • To decrease the rate of the pathway
  • To increase the rate of the pathway
  • To inhibit the activity of an enzyme
  • To regulate the flow of substrate molecules through the pathway (correct)
