B4

• Fuel for respiration

  • organisms consume and digest biomass
  • biomass is turned into glucose
  • biomass is fuel for respiration in both prokaryotic and eukaryotic organisms
• Respiration in reaction

  • respiration is a series of chemical reactions
  • it produces molecules of ATP
  • respiration releases energy, exothermic reaction
• Aerobic respiration

  • used with oxygen in mitochondria cells, 32 ATP molecules
  • Glucose + Oxygen → Carbon Dioxide + Water + Energy
• Uses of ATP respiration

  • breakdown and synthesis of molecules
  • movement
  • active transport
• Mitochondria - sub cellular structure with adaptations to allow aerobic respiration occur
• Anaerobic respiration

  • used without oxygen, in cytoplasm, 2 ATP molecules
  • in animal cells - Glucose → Lactic Acid + Energy
  • in plant cells - Glucose → Ethanol + Carbon Dioxide + Energy
