Questions and Answers

What is the main function of Complex I (NADH dehydrogenase) in the electron transport chain?

  • Transferring electrons from succinate to FAD to produce FADH2
  • Transferring electrons from NADH + H+ to Coenzyme Q and producing NAD+ (correct)
  • Transferring electrons from oxidizable substrate to FAD
  • Accepting hydrogen atom from Coenzyme Q

Which of the following is the location of the components of the electron transport chain (ETC)?

  • Inner mitochondrial membrane (correct)
  • Endoplasmic reticulum

  • Outer mitochondrial membrane

What is the role of coenzyme Q in the electron transport chain?

  • Transferring electrons from oxidizable substrate to FAD
  • Forming water at the end of the chain
