Pheromones are air-born chemicals that are sensed through olfaction. In deer, females release a sexually attractive pheromone during mating season that is sensed by male deer.Which of the following explains why only certain cells in the male deer receive pheromone signals, while the pheromones are exposed to all cells in the male deer?
|
|
All cells contain the intracellular and extracellular receptors necessary to stimulate a signal transduction pathway.
|
|
|
Only certain cells in the male (particularly cells involved in sex response) have receptors that bind to the female deer pheromone.
|
|
|
Temporal isolation causes the receptors to only be active during mating season to maximize cell energy efficiency.
|
|
|
Cell reception is different than organ processing of chemical signals.
