Chapter 7 : Respiration

Able to explain 3 common  adaptations of  thé respiratory structure

·         The number of structures is high that provide large surface area

·         The thickness of the structure is thin which  also provides the large surface area

·         The inner surface is lined with a layer of moist epithelial cells which easily dissolve the oxygen

Chemical equation in aerobic respiration:

C₆ H₁₂ O₆  +  6 O_{2 ------------------}6CO₂ + 6H₂O + energy( 2898 kJ)

(glucose)       ( Oxygen)   ( Carbon dioxide) ( Water)       

anaerobic respiration

Chemical equation in animal:

C₆ H₁₂ O_{6-----------------------}2C₃ H₆ O₃    +Energy(210 kJ)

(glucose)                  (lactic acid)

                               

anaerobic respiration

Chemical equation in plant:

C₆ H₁₂ O₆  ----------- 2C₂ H₅ OH + 2CO₂ + Energy

(glucose)               ( ethanol)  (Carbon dioxide) ( 210kJ)
