Explain energy transduction and receptor potential as they relate to the function of a sensory receptor. What will be an ideal response?
Sensory receptors convert (transduce) the energy of a stimulus into a change in membrane
potential. In particular, the energy of the stimulus causes the opening or closing of membrane
channels that alters the resting potential. This changed membrane potential is the receptor
potential. The magnitude of the change in membrane potential depends on the energy of the
stimulus, and thus the receptor potential is a graded response. Receptor potentials can
generate action potentials in sensory neurons, which transmit coded signals to the CNS
