B2, Respiraion 0.0 / 5 ? BiologyRespiration and exerciseGCSEAQA Created by: emmajane_Created on: 10-04-14 17:32 What is respiration? A series od reactions in which energy is released from glucose 1 of 15 What does 'aerobic' mean and what is the formula for it? 'with oxygen' and glucose+oxygen= carbon dioxide+ water 2 of 15 What is used up and what is wasted during aerobic exercise? Glucose and oxygen is used up/ carbon dioxide and water are the waste products 3 of 15 What is energy from respiration for plants used for? To make amino acids from sugars, nitrates and other nutrients 4 of 15 What is energy used for in animals? To enable their muscles contract 5 of 15 Why does oxygen and glucose have to be delivered to muscle cells during exercise? Because they respire more than the rest 6 of 15 Why does waste carbon dioxide have to be removed more quickly from muscle cells? Because they respire more than the rest 7 of 15 What does an increased heart rate increase and what does increased depth of breathing increase? hearth rate= increased blood flow depth of breathing= gaseous exchange in lungs 8 of 15 What do muscles store glucose as and when are they converted back? stores as glycogen and converted back when exercising 9 of 15 What is Anaerobic ecercise and what is the formula? Incomeplete breakdown of glucose and glucose= lactic acid 10 of 15 What is muscle fatigue and what is it due to? Muscles contract less effectively and due to a build up of lactic acid 11 of 15 How do fit peoples pulse rates differ to unfit peoples pulse rates? fitter peoples pulse rates do back to normal quicker than un fit peoples pulse rates 12 of 15 Why are fit people not nessecarilt healthy? Because they have to be free of disease and infection 13 of 15 What is oxygen debt? The amount of oxygen needed to oxidise lactic acid to carbon dioxide and water 14 of 15 What causes you to continue to breath deeply after exercise? Oxygen Debt 15 of 15
