- Respiration
- aerobic respiration
- the release of energy in our bodies
- every break of a glucose bond = release of energy
- controlled by enzymes
- in plants the glucose is a product of photosynthesis
- animals = the break down of food stores in the gut
- muscle contractions
- movement
- maintaining a steady body temperature
- proteinsynthesis
- building up large molecules from small ones
- growth
- every break of a glucose bond = release of energy
- mitochondria
- waste products = carbon and water
- breathing rate & depth increase
- oxygen
- heart rate increases
- to supply more oxygen to respiring cells
- the release of energy in our bodies
- anaerobic respiration
- oxygen debt
- the point after exercise when oxygen is needed to break down lactic acid
- glycogen
- store of glucose
- that is broken down and releases energy when needed
- liver
- store of glucose
- used when there is not enough oxygen
- the incomplete breakdown of glucose
- lactic acid builds up in the muscles
- oxygen debt
- aerobic respiration
