Amino acid sequences shown in orange extend carbonyl (C=O) groups toward the pore interior. K + ions (red balls in the left panel; blue balls in the right panel) unbind from the oxygens of water (in cytoplasm or extracellular Fuid) and bind to the oxygens of the carbonyl groups . Depending on the electro-chemical gradients for K
