Scope and sources
Cambridge IGCSE Biology 0610 · 2026–2028 v3 · Original learning materials.
The uses of energy in living organisms (12.1.1); investigating the effect of temperature on respiration in yeast (12.1.2); aerobic respiration and its word equation (12.2.1, 12.2.2) and balanced equation (Supplement 12.2.3); anaerobic respiration, much less energy per glucose molecule, the word equations in yeast and in muscles (12.3.1–12.3.4) and the balanced equation in yeast (Supplement 12.3.5); lactic acid and the oxygen debt, and how the debt is removed (Supplement 12.3.6, 12.3.7). The gas volumes in the experiment come from a teaching model.
Apparatus, amounts and times in the experiment are illustrative. Real practical work follows a teacher-approved safety method.
