Respiration
- ExothermicAlways in living cellsEnergy to surroundings
- AerobicGlucose + oxygenCO₂ + waterTransfers more energy
- Anaerobic in musclesGlucose → lactic acidTransfers less energy
- Anaerobic in yeast and plantsEthanol + CO₂FermentationBread, alcoholic drinks
- ExerciseHeart rate upBreathing rate upBreath volume upFatigue
- Oxygen debtHigher tierLactic acid to liverConverted to glucose
- MetabolismSum of all reactionsGlycerol + 3 fatty acidsAmino acids to proteinExcess protein to urea
