Essential Idea:  Cell respiration supplies energy for the functions of life.
At SHS, Topic 2.8 is taught in the following class unit(s):​​
2.8.U1  Cell respiration is the controlled release of energy from organic compounds to produce ATP.
  • ​Define “cell respiration.”
  • State the reaction for cellular respiration.
  • State the types of organic compounds used in cellular respiration by animals and plants.
2.8.U2  ATP from cell respiration is immediately available as a source of energy in the cell.
  • State three example uses of cellular energy.
  • Outline energy transfer in the formation and use of ATP. 
  • State three reasons why cellular respiration must be continuously performed by all cells.
2.8.U3  Anaerobic cell respiration gives a small yield of ATP from glucose.
  • ​Define “anaerobic respiration”
  • List three situations in which anaerobic respiration is useful.
  • Compare anaerobic respiration in yeasts and humans.
2.8.U4  Aerobic cell respiration requires oxygen and gives a large yield of ATP from glucose.
  • Compare the total amount of ATP made from anaerobic and aerobic respiration.
  • ​State the location of aerobic respiration.
2.8.A1  Use of anaerobic cell respiration in yeasts to produce ethanol and carbon dioxide in baking.​
  • Outline how anaerobic respiration in yeast is used in baking.
  • Outline how anaerobic respiration in yeast is used in ethanol production.
2.8.A2  Lactate production in humans when anaerobic respiration is used to maximize the power of muscle contractions.
  • State the condition in which humans would perform anaerobic respiration.
  • ​Outline production of lactate in humans during anaerobic respiration.
2.8.S1  Analysis of results from experiments involving measurement of respiration rates in germinating seeds or invertebrates using a respirometer.
  • Outline the use of a respirometer to measure cellular respiration rate.
2.8.NOS  Assessing the ethics of scientific research- the use of invertebrates in respirometers experiments.
  • List ethical questions that must be considered before using animals in experiments.
I give many of my IB Biology resources away, for the benefit of students and teachers around the world.
