  1. 1. Respiration <ul><li>Learning Objectives : </li></ul><ul><li>To understand how the role of the human respiratory system links to cellular respiration. </li></ul><ul><li>To know the reactants and products of respiration. </li></ul><ul><li>To perform a test for a product of respiration. </li></ul>

  3. 3. How is digested food used by the body? The body needs a constant supply of energy which comes from digested food. Glucose from digested carbohydrate is an important substance that contains stored chemical energy . When glucose reacts with oxygen a lot of energy is released. The release of energy from glucose is called… In the body’s cells, glucose and oxygen react to release energy . Some of this is released as heat and the rest is used by the cells. respiration
  4. 4. What is respiration? This type of respiration is called aerobic respiration because energy is released with oxygen . Respiration is the process that the body uses to release energy from digested food (glucose): carbon dioxide glucose oxygen water energy How do the glucose and oxygen needed for aerobic respiration get to the all the body’s cells? from the digestive system from the breathing system useful! waste product exhaled waste product exhaled

  8. 8. 8B Energy words Match the word to its correct meaning: 1 respiration   2 oxygen    3 carbon dioxide     4 water 5 energy 6 transport systems A is a poisonous by-product of respiration.   B take materials to and from respiring cells. C is needed to release energy from glucose in the body. D the process that releases energy from food. E is made when energy is released from food. F is needed to do anything. D the process that releases energy from food. C is needed to release energy from glucose in the body.  A is a poisonous by-product of respiration.   E is made when energy is released from food. F is needed to do anything. B take materials to and from respiring cells.
  9. 9. 8B Respiration – the truth, and quite few lies True or false? 1. Respiration means breathing. 2. Respiration occurs in all body cells. 3. Respiration gives out oxygen. 4. Carbon dioxide is used up by respiration. 5. Respiration is a chemical process that releases energy. 6. Plants do not respire. FALSE TRUE FALSE FALSE TRUE FALSE
  10. 10. 8B Respiration – the truth, and quite few lies True or false? 1. Respiration releases energy from glucose. 2. Oxygen is needed for respiration in humans. 3. We die without oxygen because we cannot respire. 4. Respiration is a bit like burning. 5. People do not respire while they are asleep. 6. The more energy we need, the less we respire. TRUE TRUE TRUE TRUE FALSE FALSE
