Energy from respiration 0.0 / 5 ? BiologyRespiration and exerciseGCSEAQA Created by: Sam EvansCreated on: 15-12-14 21:16 What does the term ' aerobic' mean? Using oxygen 1 of 10 What is meant by 'anaerobic' respiration? Respiration without using oxygen 2 of 10 What do muscle cells need more of during exercise? Energy 3 of 10 What are the two waste products of aerobic respiration? Carbon dioxide and water 4 of 10 which substances is stored in the muscles and can be converted into glucose? Glycogen 5 of 10 What is the word equation for aerobic respiration? glucose + oxygen -> carbon dioxide + water (+energy) 6 of 10 Why do muscles become fatigued (tired) during vigorous exercise? Lactic acid builds up in the muscles 7 of 10 What changes occur to the breathing and heart rate during exercise? The breathing and heart rate increases 8 of 10 Why do blood vessels in the muscles dilate during exercise? It allows a frequent flow of blood to muscles which supplies oxygen and glucose to the muscles more quickly and removes carbon dioxide faster 9 of 10 Explain what is meant by an 'oxygen debt'. The amount of oxygen needed to breakdown the lactic acid produced in anaerobic respiration 10 of 10
