Respiration
Respiration
The process of releasing energy from food using oxygen. It produces carbon dioxide, water, and energy.
Aerobic Respiration Equation
Aerobic Respiration Equation
Glucose + Oxygen → Carbon Dioxide + Water + Energy
Growth and Repair: Protein
Growth and Repair: Protein
Proteins are digested into amino acids, which are then used to build up new cells in the body.

Study Notes
Respiration
- Respiration is the release of energy from food using oxygen
- The word equation for aerobic respiration is: glucose + oxygen → carbon dioxide + water + energy
- Cells are mainly built from proteins that we get from meat or eggs
- Proteins are digested into amino acids, then transported to different cells to be used for energy
Growth and Repair
- Cells need energy to build proteins to rebuild and repair tissues.
Carbon Dioxide Detection
- Limewater turns from clear to milky when carbon dioxide is present.
- Limewater is a way to detect carbon dioxide.
- Normal air is 0.04% carbon dioxide
Human Breathing System
- The pathway of air to the lungs: nostrils → mouth → larynx → trachea → bronchi → bronchioles → alveoli
- Parts of the human breathing mechanism:
- Nostrils
- Mouth
- Larynx
- Trachea
- Bronchi
- Bronchioles
- Alveoli
- Diaphragm
- Intercostal muscles
- Lungs are in the thorax, protected by the ribcage and separated from the abdomen by the diaphragm
- It is better to breathe through your nose as the air is warmed and filtered
- Larynx: voice box, contains vocal cords; windpipe divides into two bronchi
