Questions and Answers

What is the primary function of enzymes in biological reactions?

  • To catalyze chemical reactions by lowering the activation energy (correct)
  • To regenerate ATP from ADP and Pi
  • To increase the activation energy of chemical reactions
  • To consume reactants and decrease reaction rates
  • What is the role of the active site in enzyme function?

  • To change the shape of the enzyme to prevent substrate binding
  • To hold substrates in place via weak interactions and facilitate catalysis (correct)
  • To bind reactants and increase the activation energy
  • To release products and increase the free energy
  • What is induced fit in the context of enzyme function?

  • The change in shape of the active site to accommodate substrate binding (correct)
  • The release of products from the enzyme-substrate complex
  • The increase in activation energy required for catalysis
  • The binding of multiple substrates to the active site
