Respiration- Ana+Aer

• What is respiration?


  chemical process that releases the energy from sugar molecules such as glucose
• What reaction is respiration/ en/ex


  exothermic
• How can cells use the energy from respiration?

  -build larger molecules(combining amino acids to form proteins) -Muscular Contraction(basic everyday movement) -Maintain Body Temperature(keeping warm)
• What is metabolism?


  The combination of all chemical reactions in an organsim
• What is the word equation for aerobic respiration?

  Glucose + Oxygen -> Carbon Dioxide + Water + Energy
• What is the symbol equation for aerobic respiration?

  C6H12O6+6O2=6CO2+6H20
• What is the word equation for anaerbic resperation in animals?

  Glucose → Lactic Acid + Energy
• What is the word equation for anaerobic respiration in plants/fungi?

  glucose=ethanol+carbon dioxide
• Which type releases more energy? Why?

  Aerobic releases more = doesn't break down glucose molecules completely, so it doesn't release much energy
• Why don't animals carry out aerobic respiration?

  it requires oxygen, during intense exercise there wont be enough
• How is anaerobic respiration used in making bread?

  -when making bread you add yeast in the mixture -as there is a limited oxygen in the mixture, they will respire anaerobically -this produces carbon dioxide which forms little bubbles of gas -these pockets of gas make the bread light and fluffy
