Ionotropic Receptors Protrude Outside and Inside the Cell

Question

Ionotropic receptors protrude outside and inside the cell.

Accepted Answer

Ionotropic receptors, also known as ligand-gated ion channels, have a structure that allows ions to flow into or out of the cell through a pore formed by the receptor. This pore protrudes outside and inside the cell, allowing for the movement of ions across the membrane.
