Document Summary
To perform their many tasks, living cells require energy from outside source. Energy enters most ecosystems as sunlight and leaves as heat. Photosynthesis generates oxygen and organic molecules that the mitocho respiration. Cells harvest the chemical energy stored in organic molecules and use it most cellular work. Respiration has three key pathways: glycolysis, the citric acid cycle, and o. Concept 9. 1 catabolic pathways yield energy by oxidising o. The arrangement of atoms of organic molecules represents potential ene. Enzymes catalyze the systematic degradation of organic molecules that a less energy. Some of the released energy is used to do work; the rest is dissipated as. Catabolic metabolic pathways release the energy stored in complex orga. One type of catabolic process, fermentation, leads to the partial degradat. A more efficient and widespread catabolic process, cellular respiration, co breakdown of a variety of organic molecules. In eukaryotic cells, mitochondria are the site of most of the processe.
