redox reactions

• during aerobic respiration what happens to hydrogen atoms


  they are removed from the intermediate compound and are split into protons and electrons
• in aerobic respiration what are hydrogen atoms split into


  protons and electrons
• what is meant by oxidation in terms of hydrogen


  loss of hydrogen
• what is meant by reduction in terms of hydrogen


  gain of hydrogen
• what is broken down during respiration


  glucose
• what is meant by a catabolic reaction


  this is when molecules are broken down
• what is meant by a anabolic reaction


  thsi is when molecules are built up
• is energy released or absorbed in a catabolic reaction


  released
• is energy released or absorbed in a anabolic reaction


  absorbed
• what is meant by a coenzyme


  these are complex molecules that accept and carry hydrogen from substrate molecules in respiration
• give two examples of coenzymes


  NAD and FAD
• in a redox reaction what will happen to a coenzyme


  they are reduced and will gain hydrogen
• what will NAD become after oxidation


  reduced NAD (NADH/H^+)
• what will FAD become after oxidation


  reduced FAD(FADH^2)
• in respiration what molecules act as hydrogen carriers


  coenzymes
