2. What is the equipment for measuring the rate of respiration called and what is it based on?

  • Respiro-matic, based on how fast a duck can spin on its axis
  • Respirometer, based on measuring gas volume
  • Respirometer, based on measuring distance moved by an organism
  • Respiration meter, based on measuring uptake of mass

3. What are the end products of glycolysis?

  • pyruvate, ADP and Pi, NADP
  • pyruvate, ATP, NADPH
  • triose phospate, ATP, NADPH
  • triose phospate, ADP and Pi, NADP

4. At the start of glycolysis, glucose is activated by ...................

  • Oxidation (gain of oxygen)
  • phosphorylation (bonded to 1 phosphate molecule)
  • phosphorylation (bonded to 2 phosphate molecules)
  • Reduction (gain of Hydrogen atoms)

5. What is the correct sequence of processes for aerobic respiration?

  • electron transport chain > krebs cycle > link reaction > glycolysis
  • glycolysis > link reaction > krebs cycle > electron transport chain
  • glycolysis > krebs cycle > link reaction > electron transport chain
  • glycolysis > electron transport chain > link reaction > krebs cycle
