Anaerobic and Aerobic Respiration
- RESPIRATION IS...
- NOT breathing
- The process of releasing energy
- From the breakdown of glucose
- From the breakdown of glucose
- NOT breathing
- AEROBIC RESPIRATION
- Respiration using oxygen
- Most efficient way of releasing energy
- Goes on all the time in animals and plants
- Glucose + Oxygen --> Carbon Dioxide + Water (+Energy)
- Most reactions in aerobic respiration
happen inside mitochondria
- Respiration using oxygen
- RESPIRATION RELEASES ENERGY FOR...
- Building up larger molecules
from smaller ones
- Like proteins from amino acids
- Like proteins from amino acids
- Allowing muscles to contract (in animals)
- Which allows movement
- Which allows movement
- Keeping the body temperature steady and
warm (in mammals and birds)
- Building sugars, nitrates and
other substances into amino acids
- To make proteins
- To make proteins
- Building up larger molecules
from smaller ones
- EXERCISE
- Increases heart rate because...
- More oxygen and glucose is used up
- And more carbon dioxide is taken away
- So the blood flow needs to
increase to meet this demand
- So the blood flow needs to
increase to meet this demand
- And more carbon dioxide is taken away
- More oxygen and glucose is used up
- Glycogen is used
- Some glucose is stored as glycogen
- It is mainly stored in the liver
- But some is in the muscles too
- But some is in the muscles too
- During vigorous exercise
- Muscles use glucose rapidly
- So some stored glycogen is converted to glucose to provide more energy
- So some stored glycogen is converted to glucose to provide more energy
- Muscles use glucose rapidly
- Stored as glycogen for large
surface area for enzymes to get to
- Some glucose is stored as glycogen
- Makes you breathe more deeply and
increases your breathing rate because...
- More oxygen is needed for the muscles
- More oxygen is needed for the muscles
- You get warmer
- Because tone of the by-products of respiration is heat
- So your blood vessels dilate and you sweat
- Because tone of the by-products of respiration is heat
- Increases heart rate because...
- ANAEROBIC RESPIRATION
- Glucose --> (Energy) + Lactic Acid
The incomplete breakdown of
glucose
- Respiration without oxygen
- Because your body can't supply enough
oxygen to your muscles
- Because your body can't supply enough
oxygen to your muscles
- Causes production of lactic acid
- Which causes cramp and muscle fatigue
- Removed through oxidisation which turns it
into carbon dioxide and water
- Which causes cramp and muscle fatigue
- Does not release nearly as much energy as aerobic respiration
- But it's useful in emergencies and you can
keep using your muscles for a while longer
- But it's useful in emergencies and you can
keep using your muscles for a while longer
- Oxygen debt
- You have to repay oxygen that you
didn't get to your muscles in time
- Because your heart, lungs and blood
couldn't keep up with the earlier on
- So you keep breathing hard for a while after you stop
- Because your heart, lungs and blood
couldn't keep up with the earlier on
- You have to repay oxygen that you
didn't get to your muscles in time
- Glucose --> (Energy) + Lactic Acid
The incomplete breakdown of
glucose
