Phototransduction utilizes a signal transduction cascade similar to mechanisms inspired by hormones and neurotransmitters. But, the visual sensory apparatus is stimulated by photons as well as converts light energy into a nerve impulse. Find out whether each of the following events increases photo transduction or does not increase photo transduction either by not initiating a signal or by terminating the signal. The abbreviation cGMP is utilized for guanosine 3\5\-cyclic monophosphate (cyclic GMP), and PDE is used for phosphodiesterase.
