products and the relative amounts of energy transferred. 4.4.2.1 Anaerobic respiration Anaerobic respiration in muscles is represented by the equation: The energy transferred supplies all the energy needed for living processes. As the oxidation of glucose is incomplete in anaerobic respiration much less energy is transferred than in aerobic respiration. 1 Give students the products and reactants for anaerobic respiration and ask them to recap KS3 by putting them in the correct order. Compare this equation with the one for aerobic respiration. Write the word equation for anaerobic respiration. Students can investigate the time they can continue clenching and unclenching non-writing hand above and below the level of their heart. 4.4.2.1 Fermentation Anaerobic respiration in plant and yeast cells is represented by the equation: Anaerobic respiration in yeast cells is called fermentation and has economic importance in the manufacture of bread and alcoholic drinks. 1 Ask students to recap from KS3 and write a definition for fermentation. Write the word equation for fermentation. Investigate the amount of carbon dioxide produced from fermentation of yeast with varying amounts of sugar: Use three pre-made up solutions and add different food colourings to each to prevent confusion. Use water as a control. Use the change in the diameter of a balloon to measure amount of CO2 produced.
