Problem: Chemically-gated ion channels are receptor proteins through which ions pass. A cell biologist has blocked these channels in a lab rat's liver tissue by using a chemical thata. prohibits binding of a signal molecule.b. prohibits ions from entering the cell via active transport.c. causes ions to move in the opposite direction of the ion gradient.d. prohibits second messenger signaling.
