The content for this discussion response is guided by content discussed in our textbook, Life: The Science of Biology, as well as the textbook Molecular Biology of The Cell – 5 th Edition (Alberts, . Overview In the cytosol of cells, the partial oxidation of carbohydrate molecules leads to the production of ATP, the “energy currency” of cells. Prokaryotes use their plasma membrane to produce ATP. However, in plasma membranes of eukaryotic cells, this process does not occur because they are reserved for the transportation of molecules inside and outside of cells. Consequently, eukaryotic cells rely on mitochondria to produce ATP, which are membrane-enclosed energy-converting organelles. We can find mitochondria in the cells of a large variety of organisms (e.g., animals, plants, algae, fungi and protozoa). Only in plants and algae, however, we also have chloroplasts. Mitochondria In mitochondria, there is a respiratory chain system that can be found in its inner membrane. Here, electrons pass through three enzyme complexes. Electrons are transferred via protein- bound electron carriers (e.g., hemes and iron-sulfer complexes). As they move, electrons are
