If all receptor proteins were removed from hepatocytes' (liver cells') membranes, then the liver would no longer respond to hormones. This would be catastrophic to the metabolism, because the liver could no longer process nutrients such as glucose. Such a malady would prove fatal when not eating, because the lack of glycogen, cortisol, epinephrine (and other hyperglycemic hormones) woukd lead to hypoglycemic shock, coma, and death.
Answer:
Expiermenting and Researching
Explanation:
Answer:
The incoming stimuli are converted into the electrochemical signals and are delivered to the central nervous system in form of nerve impulses for perception and interpretation.
Explanation:
The sensory receptors sense the incoming stimuli such as a change in light intensity or temperature. This stimulates the receptors. A sensory receptor converts the energy in the stimulus into a graded potential. This process is called transduction. For example, olfactory receptors of nose transduce the chemical energy of the odorant molecules into electrical energy in the form of a graded potential.
As a graded potential in a sensory neuron reaches a threshold, a nerve impulse is generated and is propagated toward the CNS for integration and perception.
