A certain peptide hormone is produced in the anterior pituitary gland located at the base of the mammalian brain. The hormone targets specific cells in many parts of the body. Which of the following best explains a possible mechanism that would allow the hormone to reach all of the target cells in the body? A B с D The hormone diffuses into target cells adjacent to the anterior pituitary gland and dif- fuses through their cell membrane. The hormone moves through plasmodesmata between cells until it has reached all cells with the correct intracellular binding sites. The hormone interacts with neurons at the base of the brain and directs signals to the target cells through the neuronal network. The hormone is released into the bloodstream, where it is transported to all cells with the correct receptors.
