Mitochondrial matters of the brain: mitochondrial dysfunction and oxidative status in epilepsy.

abstract：:The protons excreted by plant cells may arise by two different mechanisms: (1) by the action of the plasma membrane H(+)-ATPase and (2) by plasma membrane redox reactions. The exact proportion from each source is not known, but the plasma membrane H(+)-ATPase is, by far, the major contributor to proton efflux. There i...
