What is aerobic respiration?
- a chemical reaction
- happens in all living cells
- how energy is released from glucose(carbs)
Word equation for aerobic respiration
Glucose + oxygen -> carbon dioxide + water (+energy)
Chemical equation for aerobic respiration
C6H12O6 + 02 -> CO2 + H2O
Balanced chemical equation
C6H12O6 + 602 -> 6CO2 + 6H2O
6 means that there are 6 amounts of these.
What type of reaction is respiration?
Exothermic- energy released in environment using heat
Meanings:
Aerobic
Anaerobic
Aerobic- with oxygen
Anaerobic- without oxygen
Where do they come from?
Glucose
Oxygen
Corbin dioxide
Water
Food->digestive system -> circulatory system-> GLUCOSE
Oxygen in air->breathing system-> circulatory system-> OXYGEN
CARBON DIOXIDE-> circulatory system->breathing system-> air
WATER-> circulatory system->excretory system->urine/water vapour (when we breathe out)
