<span>A series of complexes from electron
donors to acceptors happen in an electron transport chain. Due to the pumping action in the chain,
protons result to having a high concentration in the intermembrane space yet a
low concentration in the mitochondrial matrix.</span>
Fission and fusion are nuclear reactions that produce energy, though they are not the same. Fission is the splitting of a heavy and unstable nucleus into two lighter nuclei. Fusion is the process where two light nuclei combine together releasing vast amounts of energy.
Im pretty sure its chemical energy because there also non renewable
