BiologyRespiration and exerciseGCSEAQA Created by: white_oCreated on: 18-05-13 21:03 What is the balanced chemical equation for aerobic respiration? C6H12O6 + 6O2→ 6CO2 + 6H2O 1 of 10 How can you measure respiration rate? Measuring consumption of oxygen or production of carbon dioxide. 2 of 10 How do you calculate RQ (Respiratory Quotient)? CO2 used divided by Oxygen produced. 3 of 10 What does RQ show? The metabolic rate. 4 of 10 What is the difference between being fit and being healthy? Fit- Involves physical exercise Healthy - Freedom from disease. 5 of 10 What is the word equation for Anaerobic Respiration? Glucoe → Lactic acid (+energy) 6 of 10 What is ATP? A substance used as energy for many processes in cells. It is produced as a result of respiration. 7 of 10 What effects the metabolic rate and why? Temperature and pH effects metabolic rate because it effects the enzymes involved in respiration. 8 of 10 Why does breathing remain heavy and pulse rate remain fast during recovery? 1) Heart rate high so blood can carry lactic acid to liver to be broken down 2) Breathing heavy to replace oxygen for aerobic respiration. 9 of 10 What is oxygen debt? The incomplete breakdown of Glucose resulting in the build up of lactic acid. 10 of 10
