What statement is true regarding the retinal pigment epithelium? Cells in the PE are the site of phototransduction Cells in the PE signal between rods and bipolar cells Cells in the PE have enzymes that convert the light-sensitive photopigments back to a useable form Cells in the PE send their axons out of the retina
