t\ l.Explain the difference between an ionotropic and a metabotropic N1? 2.What is the difference between an EPSP and an IPSP? Excitatory Postsynaptic Potential (EPSP): a graded depolarization of postsynaptic membrane in response to stimulation by a neurotransrnitter chemical. ESPSP can be summated, but they can be transmitted only over shon distancc's; they can stimulate the production of action potentials when threshold level of depolarizetion is attained. Inhibitor Postsynaptic Potential IPSP t. a hyper polarization of the postsynaptic membrane in response to a particular neurotransn:iner chemical, which makes it more difficult for the postsynaptic cell to attain the thrc:h.',ld level of depolarizaion required to produce action potentials. IPSP is responsible lor p'.rstsynaptic inhibition. 3.Describe various modalities ir rrhich neurotransmitters may stop functioning. 4. What does ACH do in the C\S l Acetylcholine(ACH) is used as an excitatory neurotransmitter by some neurons in the CNS and
