GO:0016020 A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. GO:0005247 Enables the transmembrane transfer of a chloride ion by a voltage-gated channel. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded. GO:0006821 The directed movement of chloride into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. GO:0055085 The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other. GO:0034707 An ion channel complex through which chloride ions pass. GO:0005886 The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
