Synaptic Potentials
... Remember that a neuron synapses with many other neurons. So a postsynaptic neuron can receive signals from many presynaptic neurons simultaneously. Whether or not the postsynaptic cell has an action potential depends on the summation (the additive effect) of all the incoming signals. Each active syn ...

Section 7.3 Cell Transport
... Because the cell is filled with salts, sugars, proteins, and other molecules, it is almost always hypertonic to fresh water. As a result, water tends to move quickly into a cell surrounded by fresh water, causing it to swell. Eventually, the cell may burst. In plants, the movement of water into the ...

Signal transduction
Signal transduction occurs when an extracellular signaling molecule activates a specific receptor located on the cell surface or inside the cell. In turn, this receptor triggers a biochemical chain of events inside the cell, creating a response. Depending on the cell, the response alters the cell's metabolism, shape, gene expression, or ability to divide. The signal can be amplified at any step. Thus, one signaling molecule can cause many responses.
