Respiration, Cellular Respiration, Difference between respiration and…
Respiration
Respiration in plants
Lenticels in stem
surface of roots
Where soil is wet special adaptions happen
Having much larger air spaces, hollow stems
Mangroves have aerial roots
Stomata in leaves
Contributors for discovery of gases
Priestly
Lavoisier
Mechanism of respiration
Inhalation/ Inspiration
Diaphragm Flattens
Volume of chest cavity increases
Internal pressure decreases
Air from outside comes to lungs
Exhalation/ Expiration
Diaphragm relaxes (dome shape)
Volume of chest cavity decreases
Internal pressure increases
Air goes outside from lungs
Passage of air in human respiratory system
Nostrils
Nasal Cavity
Pharynx
Larynx
Trachea
Bronchus
Bronchioles
Alveolus
2 more items...
Smaller and smaller branches
Trachea divided to 2 bronchi one to each lungs
Wind pipe to lungs
Voice box contains vocal cords
Common passage for digestive and respiratory system
Epiglottis
Ensures air and food to pass in their respective passages
The valve deflects food to stomach by partly closing
Moist lining removes dirt
Gaseous exchange
By diffusion
Co2 in blood is exchanged for O2 in alveoli
Co2 rich blood is dark red
O2 rich blood is bright red
Cellular Respiration
Presence of O2
Aerobic Respiration
In mitochondria called power house of cell
Glucose to pyruvate (3 carbon)
Fermentation (Anaerobic)
Lactic Acid + Energy (bacteria)
Ethanol + CO2 + Energy (yeast)
testing the production of Heat and CO2 in anaerobic respiration
Using boiled cooled glucose, paraffin and lime water and thermometer
Aerobic
CO2 + H2O + Energy (plants and animals)
More ATP
Absence of O2
Anaerobic Respiration
Less ATP
Each ATP provides 7200 calories of energy
Difference between respiration and combustion
Combustion is done in high temperature. Body burns at that temperature
Once combustion that can't be easily stopped. But living cells are able to control respiration
Water stops combustion. But in living cells water is present mostly even respiration happens
