  2. NADH and FADH2 carry electrons to...
  3. final step in ETC..
  4. electrons are passed from glucose to..
  5. cellular respiration
  1. a electrons and protons combine with oxygen to form water
  2. b ETC
  3. c chain of electron acceptors and donors
  4. d electron carrier molecule to an ETC then finally to oxygen
  5. e process that transfers the energy in glucose to energy in the bonds of ATP

5 Multiple choice questions

  1. 1) heat production (some energy given off during respiration is liberated as heat)
    2) liberation of Carbon dioxide
    3) oxygen consumption
  2. O2 becomes reduced
  3. 2 net ATP per glucose
  4. oxygen sucks the water drop down
  5. two NAD+, reducing them to NADH

5 True/False questions

  1. organic compounds +oxygen -->to make 6 carbon molecule called citrate


  2. 3 stages of respiration1)glycolysis (in cytoplasm)
    2) citric acid cycle (in mitochondria)
    3) ETC and ATP synthase (mitochondria)


  3. Citric acid cyclepyruvate enters mitochondrion, where it loses one CO2 and is converted to the acetyl group (2-carbon)


  4. proton gradient from ETC powers...ATP synthase, which is the enzyme that catalyzes the condensation of ADP and an inorganic phosphate to make ATP


  5. in one reaction of cycleelectrons on placed on FAD (electron acceptor), reducing it to FADH2
