 * ======**6.1 Aerobic and anaerobic respiration**====== ||
 * ====== 1  ====== || ======Define //respiration// as the chemical reactions that break down nutrient molecules in living cells to release energy.====== ||   ||   ||   ||   ||
 * ====== 2  ====== || ======State the uses of energy in the body of humans: muscle contraction, protein synthesis, cell division, growth, the passage of nerve impulses and the maintenance of a constant body temperature.====== ||   ||   ||   ||   ||
 * ====== 3  ====== || ======State the word equation for aerobic respiration.====== ||   ||   ||   ||   ||
 * ====== 4  ====== || ======Define //aerobic respiration// as the release of a relatively large amount of energy in cells by the breakdown of food substances in the presence of oxygen.====== ||   ||   ||   ||   ||
 * ====== 5  ====== || ======State the equation for aerobic respiration using symbols:======

(C6H12O6 + 6O2 → 6CO2 + 6H2O).
||  ||   ||   ||   ||
 * ====== 6  ====== || ======Define //anaerobic respiration// as the release of a relatively small amount of energy by the breakdown of food substances in the absence of oxygen.====== ||   ||   ||   ||   ||
 * ====== 7  ====== || ======State the word equation for anaerobic respiration in muscles during hard exercise (glucose → lactic acid) and the microorganism yeast (glucose → alcohol + carbon dioxide).====== ||   ||   ||   ||   ||
 * ====== 8  ====== || ======Describe the effect of lactic acid in muscles during exercise (include oxygen debt in outline only).====== ||   ||   ||   ||   ||
 * ====== 9  ====== || ======Describe the role of anaerobic respiration in yeast during brewing and bread-making.====== ||   ||   ||   ||   ||
 * ====== 10  ====== || ======Compare aerobic respiration and anaerobic respiration in terms of relative amounts of energy released.====== ||   ||   ||   ||   ||
 * ======**6.2 Gas exchange**====== ||
 * ====== 1  ====== || ======Identify on diagrams and name the larynx, trachea, bronchi, bronchioles, alveoli and associated capillaries.====== ||   ||   ||   ||   ||
 * ====== 2  ====== || ======List the features of gas exchange surfaces in animals.====== ||   ||   ||   ||   ||
 * ====== 3  ====== || ======Explain the role of mucus and cilia in protecting the gas exchange system from pathogens and particles.====== ||   ||   ||   ||   ||
 * ====== 4  ====== || ======Describe the effects of tobacco smoke and its major toxic components (tar, nicotine, carbon monoxide, smoke particles) on the gas exchange system.====== ||   ||   ||   ||   ||
 * ====== 5  ====== || ======State the differences in composition between inspired and expired air.====== ||   ||   ||   ||   ||
 * ====== 6  ====== || ======Use lime water as a test for carbon dioxide to investigate the differences in composition between inspired and expired air.====== ||   ||   ||   ||   ||
 * ====== 7  ====== || ======Investigate and describe the effects of physical activity on rate and depth of breathing.====== ||   ||   ||   ||   ||
 * ====== 8  ====== || ======Explain the effects of physical activity on rate and depth of breathing.====== ||   ||   ||   ||   ||
