Q

Aerobic respiration

A
  • with oxygen
  • happens all the time
  • Glucose + oxygen —-> carbon dioxide +water
  • releases lots of energy

Q

Invistagating respiration - germinating peas

A
  • As the peas start to grow they respire releasing heat.
  • This thermos flask is insulated, so heat is not transferred to the surroundings and we can measure the change in temperature.
17
Q

Invetigating respiration - insects

A
  • hydrogen carbonate indicator -

red and turns yellow when carbon dioxide concentration increases.

18
Q

Investigating anaerobic respiration in yeast

A

bubbled through limewater -

will turn cloudy -

This shows CO2 has been produced
