<span>A, U, C and G are the four letters of rna</span>
The options for this question are:
A. Sensory cells and sensory neurons have electrically excitable membranes that change in charge potential in response to binding an environmental signaling molecule.
B. All sensory cells and sensory neurons fire action potentials when they bind a signaling molecule.
C. Sensory cells and sensory neurons have protein receptors linked to intracellular or membrane-based signaling pathways that alter ion channel permeability.
The best answer choices are:
A & C
Sensory cells and sensory neurons have electrically excitable membranes that change in charge potential in response to binding an environmental signaling molecule.
Sensory cells and sensory neurons have protein receptors linked to intracellular or membrane-based signaling pathways that alter ion channel permeability.
Explanation:
Sensory neurons are nerve cells within the nervous system responsible for converting external stimuli from the organism's environment into internal electrical impulses.
For example, some sensory neurons respond to tactile stimuli and can activate motor neurons in order to achieve muscle contraction. Sensory receptors located in the dermis or epidermises of the skin are called cutaneous receptors. These include nociceptors and thermoreceptors.

Enzymes are regulated by more than the binding of small molecules. A second method that is used all the time by eucaryotic cells to regulate a protein's function is the covalent addition of a phosphate group to one of its amino acid side chains. These phosphorylation events can affect the protein in two important ways.
