1) What is a signal transduction - West Linn-Wilsonville School District

1) What is a signal transduction pathway?

the process by which a signal on a cell's surface is converted into a specific cellular response (a series of steps)

2) How do yeast cells communicate while mating?

chemical signaling 2 mating types: a and (alpha)

-type "a" cells secrete "a" factor -type "" cells secrete "" factor the factors bind to receptors on the other; the 2 mating factors cause the cells to grow toward each other and fuse

3) How do intercellular connections function in cell to cell communication?

both plant and animal cells have cell junctions (gap junctions in animal cells; plasmodesmata in plant cells) that, where present, directly connect the cytoplasms of adjacent cells

signaling substances dissolved in the cytoplasm can freely pass between adjacent cells
