21. Rods and cones differ in function.22. But these cells, called rods and cones , have nothing to do with resetting biological clocks. 23. Actually, it's in the minute rods and cones in our eyes that register light. 24. Guanylyl cyclase is found in the retina ( RETGC ) and modulates phototransduction in rods and cones . 25. Both rod and cone PDEs catalyze the hydrolysis of cAMP or cGMP to their 5 monophosphate form. 26. Unlike in most systems, rod and cone cells release neurotransmitters when not receiving a light signal. 27. It has to do with the physiology of the cells in the latter . rods and cones . 28. Rods and cones are both photosensitive, but respond in different ways to different frequencies of light.29. It states that the retina has only two kinds of light-sensitive cells : rods and cones . 30. It is a type of heterotrimeric G-protein with different ? subunits in rod and cone photoreceptors.
