To bombard the postsynaptic cell with more molecules of neurotransmitter, the presynaptic cell needs to increase the frequency of action potentials. Action potentials are caused by the opening and closing of ion channels in the axon membrane. They are triggered by a change in the membrane potential, and when they reach the end of the axon, they cause the release of neurotransmitters from the synaptic vesicles into the synaptic cleft. The neurotransmitters then bind to receptors on the postsynaptic cell, causing a response.The amount of neurotransmitter released by the presynaptic cell is directly proportional to the frequency of action potentials. This means that if the frequency of action potentials increases, more neurotransmitters will be released into the synaptic cleft, resulting in a stronger response in the postsynaptic cell. Therefore, to bombard the postsynaptic cell with more molecules of neurotransmitter, the presynaptic cell needs to increase the frequency of action potentials.Answer:In order to bombard the postsynaptic cell with more molecules of neurotransmitter, the presynaptic cell needs to increase the frequency of action potentials.
