J1 Science Respiration Flashcards
Learn more about aerobic and anaerobic respiration and the different factors in both types of respiration.
What is the difference between aerobic respiration and anaerobic respiration?
Aerobic respiration uses oxygen and glucose, anaerobic respiration only uses glucose with no oxygen involved
Are veins oxygenated?
No
What direction of blood flow does arteries flow in?
Away from the heart
What is the combination of oxygen and haemoglobin?
Oxyhaemoglobin
What substance is produced whenever yeast respires anaerobically?
Ethanol
When your muscles use glucose to respire anaerobially and produce lactic acid, what happens?
You feel cramps and pains in your muscles
Why do we respire anaerobically?
When our muscles don’t have enough oxygen, they use glucose.
What is the name when yeast produces ethanol via anaerobic respiration?
Fermentation
What causes oxygen and glucose to move to other cells, e.g tissue cells?
Diffusion
Give a similar definition to what respiration is.
