Question

Quizplus · Accepted Answer

Ion channels control selective transport of ions based on their size and charge. The diameter of the channel is typically just large enough to fit the particular ion being transported, and the charge of the channel's lining is often attracts ions with opposite charge while repelling those with the same charge. Electronegativity is not directly relevant to ion channel function.
