Questions and Answers

Which process captures the energy of high-energy electrons from NADH and FADH2 and ultimately generates ATP?

  • Krebs cycle
  • Oxidative phosphorylation (correct)
  • Glycolysis
  • Fermentation

    • What is the main function of the electron-transport chain in cellular respiration?

  • To release energy in the form of heat
  • To generate a proton-motive force used to power the synthesis of ATP (correct)
  • To convert glucose into pyruvate
  • To produce NADH and FADH2

    • What is the overall reaction for the flow of electrons from NADH to oxygen in cellular respiration?

  • NADH + O2 + H+ -> H2O + NAD+ + energy
  • NADH + 1/2 O2 + H+ -> H2O + NAD+ (correct)
  • NADH + O2 -> NAD+ + H2O
  • NADH + O2 -> NAD+ + H2O + energy
