- Substrate-level phosphorylation
- Oxidative Phosphorylation
Hydrogen are charged so they cant just get through the lipid bilayer. Water is everywhere and it loves the hydrogen. Animals that hibernate and babies have a pore that lets the hydrogen come back in to make heat instead of ATP. Each protein wants the electron more and more until it gets to oxygen which is an electron hog. Hydrogen is not wanted so it puts it up and creates a gradient which is not stable. Its gets relieved by going through ATP synthase. It is like a water wheel.
