Can charged ions use simple diffusion
WebTransporters transfer only those molecules or ions that fit into specific binding sites on the protein. They work with most small, water-soluble, organic molecules and a handful of inorganic ions. Channels discriminate mainly on the basis of size and electrical charge; when the channel is open, only ions of an appropriate size and charge can pass. WebExpert Answer. Ans 1 The correct answer is option (c) They're electrically charged. Explanation: Ions can be either large or small, but neither of these can cross through the …
