Document Summary
The only chemical form animal cells can use is atp (everything such as starch has to be converted to atp to be used) In plants: autotrophic they do photosynthesis and produce their own energy. Fate of pyruvate: depends of state and type of organism, plants and animals, aerobic: shuttled to mitochondrion for oxidative phosphorylation, anaerobic: fermentation happens when not enough oxygen. Any eukaryotic cells without mitochondria: red blood cells in mammals and birds but not in reptiles (they have them!) Atp (indirectly first) through the oxidative phosphorylation, but first going through the krebs cycle. Fadh2 directly: this is the general layout, but diversity in evolution results in some differences in other organisms. Not efficient, wasting a lot of energy: this energy is released as heat, not a very efficient system, evolution is not perfect. If we pump them out, we want them to stay there and not leak back.
