2.8 Cell Respiration
Nature of science:
Assessing the ethics of scientific research—the use of invertebrates in respirometer experiments has ethical implications. (4.5)
Understandings:
Cell respiration is the controlled release of energy from organic compounds to produce ATP.
ATP from cell respiration is immediately available as a source of energy in the cell.
Anaerobic cell respiration gives a small yield of ATP from glucose.
Aerobic cell respiration requires oxygen and gives a large yield of ATP from glucose.
Applications and skills:
Application: Use of anaerobic cell respiration in yeasts to produce ethanol and carbon dioxide in baking.
Application: Lactate production in humans when anaerobic respiration is used to maximize the power of muscle contractions.
Skill: Analysis of results from experiments involving measurement of respiration rates in germinating seeds or invertebrates using a respirometer.
