Document Summary
Reduced organic compounds are mobilized and subsequently oxidized in a controlled (stepwise) manner. 60 adp + 60 pi 60 atp + 60 h2o. Ie. releases energy stored in c compounds for cellular use. Energy released during oxidation transiently stored as atp. Most reactions similar across eukaryotes but some differences. Opposite of photosynthesis: reduced compounds (sucrose) oxidized to co2, o2 = ultimate e- receptor; reduced to h2o. Occurs in all living organisms: plants and animals similar (some exceptions ie. sucrose vs glucose) 1 sucrose 2 hexose phosphates 4 triose phosphates. Triose phosphate oxidized and rearranged pyruvate: energy-conserving phase. In preparation for oxidation in the citric acid cycle: yields a small amount of energy (atp, nadp) Initial phase of glycolysis: carbon substrates from different sources are channeled into triose phosphate. For each molecule of sucrose that is metabolized, 4 triose phosphate molecules are formed. Consumes 2-4 atp (synthase vs invertase pathway)/ sucrose.
