At the inner mitochondrial membrane, a high energy electron is passed along an electron transport chain. The energy released ... through the membrane, through ATP synthase. As this happens ...

These are mitochondria of several distantly related unicellular eukaryotes (protists) that lack an electron transport chain altogether. They synthesize ATP from pyruvate breakdown via simple ...

ATP (adenosine triphosphate) is the energy-carrying molecule used in cells because it can release energy very quickly. Energy is released from ATP when the end phosphate is removed. Once ATP has ...
