Cell respiration supplies energy for the functions of life
Cell respiration supplies energy for the functions of life
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:
- 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.
Skills:
- Skill: Analysis of results from experiments involving measurement of respiration rates in germinating seeds or invertebrates using a respirometer.
Nature of science
- Assessing the ethics of scientific research—the use of invertebrates in respirometer experiments has ethical implications. [covered by 2.8.S1]
