A research team discovers that a particular growth factor can bind to two different receptor types on the same cell: Receptor X (a receptor tyrosine kinase) and Receptor Y (a G-protein coupled receptor). When only Receptor X is functional, the cell proliferates rapidly. When only Receptor Y is functional, the cell undergoes apoptosis. When both receptors are functional simultaneously, what would be the most likely outcome?
