What is glucose ?
a major source of energy for most cells in the body.
What is aerobic respiration ?
the process of releasing energy from glucose, using oxygen.
What is anaerobic respiration ?
the process of releasing energy from glucose, without oxygen.

What is oxygen debt ?
The amount of oxygen needed at the end of a physical activity to break down any lactic acid .
Where does the human energy source come from ?
Fats and carbohydrates
What type of respiration does carbs and fats effect ?
Carbohydrates - anaeobic and aerobic exercise
Fats - aerobic moderate exercise
What are the different components fats have ?
- they provide most of the bodys energy
- they can be broken down into fatty acids which is absorbed into the blood
What type of food can we see fats in ?
- Butter cooking oils
- Can also be found in bacon , cheese and nuts
