Explanation
Cellular respiration releases energy from glucose: C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP energy. This is the reverse of photosynthesis. All living cells respire continuously.
Aerobic respiration (with oxygen) produces 36-38 ATP per glucose. Anaerobic respiration (without oxygen) produces only 2 ATP, plus lactic acid (animals) or ethanol (yeast).
Respiration occurs in mitochondria. The energy released (ATP) powers all cell activities – movement, growth, transport, synthesis. Do not confuse cellular respiration with breathing (gas exchange).
