E.g. walking/jogging 1 of 8 What is anaerobic respiration? Not using oxygen. High intensity for a short period of time. E.g. sprinting 2 of 8 Word equation for aerobic exercise Glucose + Oxygen ---- energy + carbon dioxide + water 3 of 8 Word equation for anaerobic exercise Glucose ---- energy + lactic acid 4 of 8 What happens during aerobic exercise? The reaction provides energy for activity and produces water and carbon dioxide as waste products. It uses oxygen to breakdown foos e.g. glucose 5 of 8 What happens during anaerobic exercise? Glucose in not fully broken down to carbon dioxide and water, instead converted into lactic acid while producing the energy needed. No oxygen is used 6 of 8 What does EPOC stand for? Excess Post-exercise Oxygen Consumption 7 of 8 What are the immediate effects of exercise (during exercise)? Heart beats faster, increased stroke volume and increased cardiac output. Also breathing rate increases 8 of 8
