The giant squid axon has a diameter = 1mm and 1 = 13mm. Compared to a mammalian neuron with a diameter = 1 um and ^ = 0.2mm, which of the following is correct? graded potentials can generate action potentials in the mammalian axon but not in the squid axon. graded potential of similar magnitude would result in action potentials with larger amplitude in the mammalian axon graded potentials of similar magnitude would result in action potentials with larger amplitude in the squid axon graded potentials of similar magnitude would travel furthest from their point of origin in the mammalian axon graded potentials of similar magnitude would travel furthest from their point of origin in the squid axon

Choosing one neurotransmitter, discuss neurotransmission from synthesis to release in the presynaptic neuron to binding and generation of a postsynaptic potential in the postsynaptic neuron.
If action potential propagation from one neuron to another neuron requires ACh release, what event at the synaptic cleft explains the need for action potentials to arrive at a high rate before the post-synaptic membrane achieves threshold? the lack of sodium voltage gated channels on the post-synaptic membrane O the rapid breakdown of ACh by ACHE at the synaptic cleft the slow release of ACh by the synaptic vessicles the slow movement of sodium through chemical gates Previous Next MacBook Air
Correct answer: Ligand-gated ion channel don’t open until the neurotransmitter diffuses across the synapse and binds to the receptor, The calcium channels are blocked in the presynaptic cells, It takes time for the vesicular exocytosis to occur Please explain why each of the correct answer choices are correct. Thank you.

The membrane potential in animal cells, but not in plants, depends largely on resting K+ channels. How do these channels contribute to the resting membrane potential? Why are these channels considered to be nongated channels? How do these channels achieve selectivity for K+ versus Na+, which is smaller than K+?
