How does a hormone qualify as a long-distance signaling example? 5. A signal transduction pathway has three stages. WebMating in yeast is stimulated by the presence of a pheromone which binds to either the Ste2 receptor (in a-cells) or the Ste3 receptor (in α-cells). The binding of this pheromone then leads to the activation of a heterotrimeric G protein.
