Endothermic reactions - take in energy from surroundings - e.g Glucose stored as starch/glycogen <> Glucose converted to cellulose <> Glucose combined with nitrate ions to form amino acids <> Amino acids linked to form proteins <> Glycerol combined with 3 fatty acids to form lipids
Exothermic reactions - transfer energy to the surroundings - e.g respiration <> breaking down excess protein into urea

Aerobic (takes place in the mitochondria) Complete breakdown/oxidation
Glucose + Oxygen -> Carbon Dioxide + Water (+38 ATP molecules)
C6H12O6 + 6 O2 -> 6 CO2 + 6H2O
(+38 ATP Molecules)
Anaerobic (takes place during vigorous activity) Incomplete breakdown
Glucose -> Lactic acid (+2 ATP molecules) [in muscles]
Glucose -> Ethanol + Carbon Dioxide (+2 ATP molecules) [in plants and fungi]
^ Fermentation
(Bread + Alcoholic drinks)
