Budding yeasts use a secreted signaling molecule to find another haploid yeast cell ready to mate. What is this molecule called?

1. Budding yeasts participate in a process similar to sexual reproduction between two haploid cells. 2. To find another haploid yeast cell prepared to mate, budding yeasts secrete a signaling molecule called mating factor. 3. When mating factor binds cell-surface receptors on nearby yeast cells, those cells stop their normal growth cycle and begin a signaling cascade. 4. Autoinducers are instead the signaling molecules used by bacteria in quorum sensing, a different system. _Source: OpenStax Biology (1st ed., CC BY 4.0), Ch 9 "Cell Communication", section Signaling in Yeast_
