4.4.2.1 aerobic and anaerobic respiration

• What is respiration?

  The process of transferring energy from glucose which happens in every cell
• what type of reaction is respiration?

  exothermic
• what is the word equation for aerobic respiration?

  Glucose + Oxygen —> Carbon Dioxide + Water + Energy
• what is the most important product of respiration?

  energy
• what do organisms need energy for?

  • chemical reactions to build larger molecules
  • movement
  • keeping warm
• what is aerobic respiration?

  respiration using oxygen
• when does aerobic respiration happen?

  all the time in animals and plants
• where does most of aerobic respiration happen?

  in the mitochondria
• what is the symbol equation for aerobic respiration?

  $C_6H_{12}O_6+$$6O_2$ —> $6CO_2+$$6H_2O$
• when do you use anaerobic respiration?

  if theres not enough oxygen
• what is the word equation for anaerobic respiration in animals?

  glucose —> lactic acid
• why doesn’t anaerobic respiration transfer as much energy as aerobic?

  glucose isn't fully oxidised
• when is anaerobic respiration useful?

  in emergencies
• what is the word equation for anaerobic respiration in plant and yeast cells?

  glucose —> ethanol + carbon dioxide
