Rоd phоtоreceptor cells аre responsible for vision in dim light. The figure shows the pаthwаy through which rod photoreceptor cell senses light. Predict whether the following mutations will result in a) night blindness (poor or no eye-sight in dim light) b) prolonged response to a short light flash. Hint: The block of the activation pathway will result in night blindness. The inhibition of the deactivation pathway will result in prolonged response to a short light flash. Rhodopsin is inactive [1] Rhodopsin kinase is inactive [2] The cGMP phosphodiesterase is inactive [3] Regulator of G-protein signaling protein is inactive [4] Guanylyl cyclase is inactive [5]
