  1. Respiration Revision Questions W. McConnell 2004 Kinross High School

  2. 1. Where does respiration take place? Answer: In all cells W. McConnell 2004 Kinross High School

  3. 3. What is meant by the term ‘respiration’? Answer: The chemical process by which energy is released from food.

  4. 4. What is the main source of energy in a cell? Answer: Glucose

  5. 3. Name 4 things that cells need energy for. Answer: • Cell division • Heat production • Movement • Chemical reactions W. McConnell 2004 Kinross High School

  6. Give 2 ways that energy can be stored in cells 4 Answer • Fat • Carbohydrate W. McConnell 2004 Kinross High School

  7. 5 Name 3 places that energy can be stored in humans. Answer • Liver - (glycogen) • Muscles - (glycogen) • Under skin – (fat) W. McConnell 2004 Kinross High School

  8. 5. How do plants obtain their glucose? Answer: They make glucose by photosynthesis.

  9. 6 In what form do plants store their energy. Answer In the form of starch W. McConnell 2004 Kinross High School

  10. 1. What energy change takes place when food burns? Answer: Chemical energy to heat energy.

  11. 7 The diagram below shows the apparatus to find the energy in different foods. thermometer food sample water heat Name 2 variables which must remain constant if you were testing different foods. • Volume of water • Mass of food

  12. 2. What unit is used to measure the heat energy given off from food? Answer: Kilojoules

  13. 9. Which food type contains most energy? Answer: Fat W. McConnell 2004 Kinross High School

  14. 10. In the experiment to find out which food type gave out most heat energy, give 2 sources of error when carrying out the experiment. Answer • Some heat lost to air • Food not completely burnt W. McConnell 2004 Kinross High School

  15. 11. How would it be possible to make sure that all the food had been completely burnt? Answer Supply oxygen to the food when burning it. W. McConnell 2004 Kinross High School

  16. 12. Which chemical absorbs carbon dioxide? Answer Potassium Hydroxide W. McConnell 2004 Kinross High School

  17. 13. What are the 2 raw materials involved in respiration? Answer • Glucose • Oxygen W. McConnell 2004 Kinross High School

  18. 14. Name the 2 waste products produced from respiration. Answer • Water • Carbon dioxide W. McConnell 2004 Kinross High School

  19. 15. What colour does bicarbonate indicator show when carbon dioxide is present? Answer Yellow W. McConnell 2004 Kinross High School

  20. 16 What does the word metabolism mean? Answer All the chemical reactions which happen inside a cell. W. McConnell 2004 Kinross High School

  21. Which gas is taken in and given out by living cells during aerobic respiration? 17. Answer • Gas taken in ? • Gas given out ? oxygen carbon dioxide W. McConnell 2004 Kinross High School

  22. What is meant by aerobic respiration? 18. Answer: The breakdown of glucose in cells in the presence of oxygen. W. McConnell 2004 Kinross High School

  23. Where do green plants get their energy from? 19. Answer: The sun
