Step 1
Ionotropic receptors are direct receptors that form ion channels and allow ions to flow through them when activated. Metabotropic receptors are indirect receptors that activate signaling pathways through G-proteins and second messengers, which typically take Show more…

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
