EOG818F3M GO:0005741 12/12 mitochondrial outer membrane cellular_component "The outer, i.e. cytoplasm-facing, lipid bilayer of the mitochondrial envelope." [GOC:ai] EOG818F3M GO:0008308 12/12 voltage-gated anion channel activity molecular_function "Enables the transmembrane transfer of an anion by a voltage-gated channel. An anion is a negatively charged ion. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded." [GOC:mtg_transport, GOC:vw, ISBN:0815340729] EOG818F3M GO:0006811 1/12 ion transport biological_process "The directed movement of charged atoms or small charged molecules into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore." [GOC:ai] EOG818F3M GO:0015288 1/12 porin activity molecular_function "Catalysis of the transfer of substances, sized less than 1000 Da, from one side of the membrane to the other. The transmembrane portions of porins consist exclusively of beta-strands which form a beta-barrel. They are found in the outer membranes of Gram-negative bacteria, mitochondria, plastids and possibly acid-fast Gram-positive bacteria."

[GOC:ai] EOG818F3M GO:0005739 1/12 mitochondrion cellular_component "A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration." [GOC:giardia, ISBN:0198506732]
