3.7.1 Define cell respiration
A controlled release of energy, in the form of ATP, from the oxidation of organic molecules in cells

3.7.2 State that, in cell respiration, glucose in the cytoplasm is broken down by glycolysis into pyruvate, with a small yield of ATP
• Glycolysis is the first step of respiration
• 6C glucose 2 x 3C pyruvate

3.7.3 Explain that, during anaerobic cell respiration, pyruvate can be converted in the cytoplasm into lactate, or ethanol and carbon dioxide

3.7.4 Explain that, during aerobic cell respiration, pyruvate can be broken down in the mitochondrion into carbon dioxide and water with a large yield of ATP
