The Respiratory System — Question 8

(a) Aerobic respiration
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + 38 ATP + 420 kcal

(b) Anaerobic respiration in plants
C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂ + 2ATP

(c) Anaerobic respiration in animals
C₆H₁₂O₆ → 2C₃H₆O₃ (lactic acid) + 2ATP

(d) Photosynthesis
6CO₂ + 12H₂O $\xrightarrow[\text{chlorophyll}]{\text{sunlight}}$ C₆H₁₂O₆ + 6H₂O + 6O₂↑

(e) Phosphorylation
ADP + P_i (inorganic phosphate) → ATP
