Essential Idea:
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:
- Use of anaerobic cell respiration in yeasts to produce ethanol and carbon dioxide in baking
- Lactate production in humans when anaerobic respiration is used to maximise the power of muscle contractions
Skills:
- Analysis of results from experiments involving measurement of respiration rates in germinating seeds or invertebrates using a respirometer
