What event is responsible for the conversion between cis and trans configurations of retinal? - the opening of Na+ channels - activation of a G protein - the absorption of light - activation of the enzyme phosphodiesterase - adaptation Which of the five types of taste sensations is the most sensitive? - bitter - salty - sweet - umami - sour Perception is: - Receiving signals by the receptors - Transducing signals to CNS - Changing cell membrane potential - Brain construction of the stimulus In sensory adaptation: - The receptor responsiveness to the stimuli decreases - The receptor responsiveness to the stimuli increases - The receptor responsiveness to the stimuli decreases and then immediately increases - The receptor responsiveness to the stimuli does not change Pain receptors: - Do not exist in humans - Do not exist in animals - Are called nociceptors - None of the above
