WebCellular respiration evolved after early photosynthesizing bacteria began providing a steady source of oxygen, and became abundant once oxygen began to accumulate in the ocean and atmosphere. The earliest forms of life, and some bacteria today, only use anaerobic processes (respiration without oxygen) to produce energy. Web23 de jun. de 2016 · As the site of cellular respiration, mitochondria convert the energy of organic molecules from digestion (glucose) into energy that can be directly used by the cell (ATP) during the “Krebs cycle”. ...

"The First Cell arose in the previously prebiotic world with the coming together of several entities that gave a single vesicle the unique chance to carry out three essential and quite different life processes. These were: (a) to copy informational macromolecules, (b) to carry out specific catalytic functions, and (c) to couple energy from the environment into usable chemical forms. These would foster subsequent cellular evolution and metabolism. Each of these three essentia… "The First Cell arose in the previously prebiotic world with the coming together of several entities that gave a single vesicle the unique chance to carry out three essential and quite different life processes.
