2 f) respiration Flashcards
1
Q
what is respiration?
A
the process that releases energy into every living cell of every organism. This energy is essential for keeping the cell alive as it powers processes like growth, repair and division
2
Q
respiration formula
A
Oxygen + Glucose → Carbon Dioxide + Water 6O2 +
C6H12O6 → 6CO2 + 6H2O
3
Q
what is anaerobic respiration?
A
- Some cells have the ability to respire without using oxygen
- Only liver and muscle cells can do this in humans
- Anaerobic respiration allows the cell to carry on working despite there being a shortage of oxygen, this is very useful in muscle cells whilst doing exercise such as running.
4
Q
anaerobic respiration formula
A
Glucose → Lactic Acid
C6H12O6 → 2CH3CHOHCOOH
5
Q
what does anaerobic respiration produces lactic acid?
A
It produces lactic acid, which is poisonous. It builds up inside muscle cells and quickly leads to muscle fatigue and cramp. Eventually the muscle cell will stop working.
