All the chemical reactions happening in your body building up and breaking down molecules.
What is respiration
The chemical reaction that causes the release of energy from glucose as it is broken down.
What is the word equation for aerobic respiration
Glucose + oxygen → water + carbon dioxide
What is the balanced symbol equation for aerobic respiration
C6H12O6 + 6O2 → 6H2O + 6CO2
What is the word equation for anaerobic respiration
Glucose → lactic acid (+small amount of energy)
What is the symbol equation for anaerobic respiration
C6H12O6 → 2C3H6O3
List the three main adaptations of the alveoli
large surface area, thin walls, good blood supply
Why is less energy released during anaerobic respiration
The breakdown of glucose is incomplete
What does the body use if it does not have enough glucose
Glycogen
What is oxygen debt
The amount of extra oxygen needed to break down the lactic acid
What two products are produced with fermentation
Bread , alcoholic drinks
