Question
Chapter 43.7, Problem 12LO
Summary Introduction
To compare: The two types of photoreceptors, describe the signal transduction pathway that is activated when rhodopsin responds to light, and summarize the visual pathway.
Introduction: Photoreceptors receive the light rays and convert these light rays to signal impulses. These signal impulses are generated at the neuronal linkages between these photoreceptors and dendrites of a neuron. Hence, the signals are sent by the signal transduction pathway.

Detail the separate mechanisms activated in photoreceptor cells in the presence and in the absence of light.
Describe the steps involved in vertebrate phototransduction by photoreceptors and further retinal processing by bipolar and ganglion cells.
In a detailed essay, Explain the process of phototransduction and signal transmission in the retina.
Be sure to include the steps associated with the formation/breakdown of Rhodopsin as well as the signal transduction process that takes place in the retina beginning in the dark.
Be sure to also include where in the retina these process are taking place (i.e rods, bipolar cells or ganglion cells, outer segment, inner segment...).
Please provide step-by-step details! please be sure you add all required info.
