When ______ is released, the subsequent receiving neuron ________ fire because that neurotransmitter is _______.
a.
GABA/will not/inhibitory
b.
GABA/will/excitatory
c.
Glutamate/will/inhibitory
d.
Glutamate/will not/excitatory
GABA/will not/inhibitory
Hmm, let's see if I can tickle your brain with a funny answer!
The correct answer is d. Glutamate/will not/excitatory. So, when glutamate is released, the subsequent receiving neuron says, "Oh no no, I won't fire because that neurotransmitter is not excitatory. Let's keep things chillin' here." It's like the neuron is saying, "Excitatory? Nah, I'm too cool for that."
Remember, laughter is the best neurotransmitter!
The correct answer is:
c. Glutamate/will/inhibitory
To determine the correct answer, we need to understand the role of neurotransmitters in the communication between neurons.
Neurotransmitters are chemicals that carry signals across the synapse, the small gap between two neurons. When an electrical signal reaches the end of a neuron (pre-synaptic neuron), it stimulates the release of neurotransmitters into the synapse. These neurotransmitters then bind to receptors on the receiving neuron (post-synaptic neuron), causing it to either fire or not fire an electrical signal.
In the given question, we are provided with two neurotransmitters, GABA and glutamate, and we need to identify their effects on the subsequent receiving neuron.
GABA (gamma-aminobutyric acid) is an inhibitory neurotransmitter, which means it suppresses the activity of the receiving neuron, making it less likely to fire. Inhibitory neurotransmitters generally hyperpolarize the receiving neuron, making it more negative and more resistant to stimulation. Therefore, if GABA is released, the subsequent receiving neuron will not fire, as indicated by option a. GABA/will not/inhibitory.
Glutamate, on the other hand, is an excitatory neurotransmitter, which means it promotes the firing of the receiving neuron. Excitatory neurotransmitters generally depolarize the receiving neuron, making it more positive and more susceptible to stimulation. Therefore, if glutamate is released, the subsequent receiving neuron will fire, as indicated by option d. Glutamate/will not/excitatory.
So, the correct answer is option d. Glutamate/will not/excitatory.
