12. Respiration

Nota:

• muscle contraction protein synthesis cell division active transport growth the passage of nerve impulses and the maintenance of a constant body temperature (MRS GREN)

Nota:

• The chemical reactions in cells that use oxygen to break down nutrient molecules to release energy

Nota:

• glucose + oxygen --> carbon dioxide + water the balanced chemical equation as C6H12O6 + 6O2 --> 6CO2 + 6H2O (some of these numbers should be subscript!!) 

Nota:

• on the rate of respiration of germinating seeds

Nota:

• such as arthropods and germinating seeds

Nota:

• as the chemical reactions in cells that break down nutrient molecules to release energy without using oxygen

1. in muscles during vigorous exercise

   Nota:

   • word equation: glucose --> lactic acid
2. in the microorganism yeast

   Nota:

   • word equation: glucose --> alcohol + carbon dioxide balanced chemical equation:  C6H12O6 --> 2C2H5OH + 2CO2 (some of these numbers should be subscript)

Nota:

• per glucose molecule than aerobic respiration

Nota:

• in muscles and blood during vigorous exercise causing an oxygen debt

Nota:

• limited to: - aerobic respiration of lactic acid in the liver - continuation, after exercise, of fast heart rate to transport lactic acid in blood from muscles to the liver - continuation, after exercise, of deeper breathing supplying oxygen for aerobic respiration of lactic acid
