When succinate dehydrogenase feeds two electrons directly into the mitochondrial electron transport chain and the electrons are ultimately picked up by the terminal electron acceptor, protons are pumped across a membrane. Where are the protons pumped? Identify which ETS complexes pump protons as a result of these two electrons reaching the terminal electron acceptor. Where are the protons pumped?
