Our enzymes are pretty good at choosing the right energy carrier that leads to the best efficiencies. What is the relationship between Commerce and economics? ATP can also be produced without oxygen (i.e., anaerobic), which is something plants, algae, and some bacteria do by converting the energy held in sunlight into energy that can be used by a cell via photosynthesis. How can I learn React Language | Julio Herrera? When there's a lot of ATP, though, phosphofructokinase (and other enzymes like it) will slow down. Why is more energy produced when NADH donates electrons to the electron transport chain compared to when FADH2 donates electrons? Without ATP, cells wouldn't have a source of usable energy, and the organism would die. If you think about it, you actually need energy to break any bonds, including that one (otherwise it would fall appart and not be a bond that keeps atoms together!).
