Cell signaling is how our cells communicate. Our cells must constantly be receiving cells signals to survive, otherwise they will die. Other than signals to survive or die, our cells also receive signals to do things like differentiate, grow and to divide. Cells are not limited to receiving one signal at a time and in fact don’t, receiving multiple signal at the same time. It is possible for the same signal to be received by the same receptor on cells but depending on what the cell type is will affect the outcome in the cell. This allows for one stimulus to apply a signal that many different cells can receive and can cause different actions. Longer pathways allow for more outcomes from a signal. Signal amplification can be applied to signals that travel along multiple steps in a transduction cascade and with more components in the pathway there can be more crosstalk. However, shorter step pathways are still helpful when a signal needs to be transduced fast.
