Question
1.) Imagine a neuron in which the synthesis of just one protein was inhibited. If this protein were calmodulin, then would the neuron be capable of neurosecretion?
a.) yes, neurons contain redundant calcium binding proteins
b.) no, calmodulin is a switch that initiates the signal amplication upon which neurosecretion depends
2. Identify the ligand that induces IPSPs upon post-synaptic membranes.
a.) glutamate b.) glycine
3.)A small-amplitude, graded waveform is generated each time ligand-gated Na+ channels open on adendrite in response to glutamate. This type of waveform is called an
a.) excitatory post-synaptic potential
b.) inhibitory post-synaptic potential
Explanation / Answer
A is the right answer, these are called calium sensor proteins
glycine and it is the main inhibitory neurotransmitter for nervous system of vertebrates
Inhibitatoy post synaptic potential. Also called negative transmission. GABA is the main neurotransmitter used.
