GCSE AQA Biology. Aerobic and
anaerobic respiration
What does aerobic respiration need plenty of? - answer oxygen
What is aerobic respiration? - answer respiration using oxygen
When does aerobic respiration happen? - answer all the time in plants and animals
Where do most reactions for aerobic respiration take place? - answer inside
mitochondria
What is the word equation for aerobic respiration? - answer glucose + oxygen --->
carbon dioxide + water
What is the symbol equation for aerobic respiration? - answerC6H12O6 + 6O2 --->
6CO2 + 6H2O
When is anaerobic respiration used? - answer if there's not enough oxygen
When is the most common time that anaerobic respiration takes place? – answer when
you do vigorous exercise and your body can't supply enough oxygen to your muscles,
they start doing anaerobic respiration as well as aerobic respiration
What is anaerobic respiration? - answer “without oxygen". It's the incomplete
breakdown of glucose, making lactic acid
What is the word equation for anaerobic respiration? - answer glucose ---> lactic acid
What doesn't anaerobic respiration do? - answer does not transfer nearly as much
energy as aerobic respiration
Why doesn't anaerobic respiration transfer as much energy as aerobic? - answer
because glucose isn't fully oxidized (because it doesn't combine with oxygen
When is anaerobic respiration useful? - answer in emergencies e.g. during exercise
when it allows you to keep on using your muscles a little while longer
Can plants and yeast cells respire without oxygen? - answer yes but they produce
ethanol(alcohol) and carbon dioxide instead of lactic acid
