A receptor that continues to fire long after the stimulus is applied would be classified as
a. Phasic
b. Tonic
c. Ligand-gated.
d. Voltage-gated
e. Long-term potentiation
e.) Long term potentiation
Long term potentiation means continuous increase in signalling after the initial stimulus is applied. This is usually seen in neurons which leads to continued response.

8- Which of the following can be activated by an inhibitory neurotransmiter on the postsynagtie a. Ligand-gated Na·Channels. b. Voltage-gated Na channels c. Voltage-gated K' channels d. Voltage-gated CaChannels Ligand-gated CT channels. 9- Saltatory conduction occurs when a. Sodium ions levels are highest b. Gated-sodium channels open c. The resting potential fails to be reset d. There is no synapse and the axon is continuous with the next dendrite e. The action potential jumps from node to node on a...
2. Long-term Potentiation is a process that strengthens the transmission of a single synapse in a circuit. This is achieved when pre-synaptic cells and post-synaptic cells fire action potentials at the same time. Usually multiple pre-synaptic cells synapse onto one post-synaptic cell, increasing the probability of inducing an action potential in the post- synaptic cell. You may need to refer to your textbooks or online resources for this question, as we do not cover this in explicit detail in class....

Please help me with several of these questions, thank you very much. 1. During the propagation of an action potential along the axon of a neuron, what is happening at the leading edge (the front) of the region of depolarization as it moves down the axon? a. Ligand-gated Na+channels are opening. b. Voltage-gated Na+channels are opening. c. Ligand-gated K+channels are opening. d. Voltage-gated Na+channels have become inactive and refractory. e. Voltage-gated Na+channels are closing. 2. During transcellular transport of glucose...
In the above scenario, you introduce a dominant-negative dynamin CNDA into the cells. What might happen after 10 minutes of treatment with ligand? A. The ligand and the receptor would not enter the cell and localize as dots. B. The ligand and receptor would appear as overlapping red green dots similar to control non mutant dynamin cells. C. The ligand and receptor would stay as overlapping dots even after 20 minutes of treatment. D. None of the above. E. All...

Question 1 (1 point) Vasoconstriction occurs when epinephrine (adrenaline) binds to the a-adrenergic receptor on vascular smooth muscle cells. One way to treat high blood pressure is to administer competitive inhibitors that bind to this receptor. The Kd for binding of epinephrine to this receptor is ~UM. Based on the measured affinity (Kd) of the following drugs for the a-adrenergic receptor, which might be good candidates for high blood pressure medication? Drug A: Kd = 0.6 M; Drug B: Kd...
