Question
Chapter 15.3, Problem 28AYP
Summary Introduction
To analyze:
The pathway of the action potential from the rod or cone cell to the optic nerve.
Introduction:
After the absorption of light by the rhodopsin molecule, the shape of the opsin changes from 11-cis-retinal to all Trans retinal. This change leads to the activation of the attached g-protein known as transducin.
