The type of neurotransmitter.
Presynaptic neurons release the neurotransmitter in response to an action potential. Postsynaptic neurons receive the neurotransmitter (and can however become presynaptic to the next nerve cell, if the neurotransmitter has stimulated the cell enough).
Exercise helps to increase the production and release of endorphins. This is part of the sympathetic response of the body also sometimes called the flight-or-fright response that prepares the body for coping with danger. In the case of endorphins they reduce the sensation of pain so the person can keep fighting or running away hopefully long enough to reduce or eliminate the stressful threat, or just a normal result of physical activity is that some endorphins will be released. Sometimes this is called the 'runner's high.'
