Step 1: Ionotropic receptors are fast receptors because they directly open ion channels when a ligand binds to them. Show more…

Determine whether each is true of metabotropic or ionotropic receptors They use second messengers. They are ion channels. Effects begin quickly Effects are widespread around the neuron. Effects last longer Effects are localized to a small area of the membrane. Usually depends on glutamate and GABA Associated with taste, smell, pain Use many different neurotransmitters Associated with attention, arousal emotion, Associated with vision and hearing.

QUESTION 8 What are the two general types of transmitter receptors? metabotropic receptors, which are receptors coupled with g-proteins amino acid receptors ionotropic receptors, which are the ligand-gated channels small molecule receptors QUESTION 9 When comparing ionotropic receptors to metabotropic receptors, which of the following is true for ionotropic receptors? (check all that apply). after the transmitter binds to the receptor, the effect on the post synaptic membrane potential has a delay relative to metabotropic receptor action. after the transmitter binds to the receptor, the effect on the post synaptic membrane potential is relatively fast the action that leads to a change in the membrane potential is relatively long lasting (long duration) the action that leads to a change in the membrane potential is relatively short lasting (short duration) QUESTION 10 (from the slide set) When comparing ionotropic receptors to metabotropic receptors, which of the following is true for ionotropic receptors? (check all that apply). the amplitude of the potential can be relatively large for a psp (e.g., 10 mV) the amplitude of the psp is relatively small the postsynaptic potential can be measured in milliseconds the postsynaptic potential can be measured over seconds to minutes

Which of the following is TRUE about ionotropic vs metabotropic receptors? A. Metabotropic receptors are ion channels. B. When ionotropic receptors are activated they can cause an immediate change in the voltage across the membrane of the receptor neuron. C. Ionotropic receptors are coupled to G proteins and thus indirectly to ion channels. D. Metabotropic receptors activate second messenger systems and as such their effect is very short-lived (immediate).
