WebWhen retinal absorbs a photon, the double bond between the 11th and 12th carbon atoms flips, thus reconfiguring the molecule from the 11- cis to the all- trans form. This in turn triggers a molecular transduction cascade, resulting in the closure of sodium channels in the membrane and hyperpolarization (increase in negativity) of the cell.
