1) Ion channels in the plasma membrane open and close in response to chemical before changing their conformation to form a passageway through the membrane. These ion channels are specific to particular ions. 2) Protein kinase receptors catalyze the phosphorylation of themselves and other proteins when activated, thus changing their shapes and functions. 3) The G protein linked receptor is involved in communication between cells for sensory information. The G protein is the intermediary between the receptor and its effectors by binding to the receptors, GTP and effectors.
