If the result of a second messenger activation is to increase K channel opening in the postsynaptic neuron, how will the excitability of the postsynaptic neuron change? Explain your answer.
Homework Answers
Ans:- In that case the postsynaptic neuron will become depolarized.
Explanation:- Opening of the K channels allows the leakage of the K out of the cell and hence the Na channels are opened allowing the Na ions to move into the neuron and thus become depolarized.

The right answer is (D)
Please explain. I don't understand how K+ could be effluxing rather

Passage IV (Questions 114-117) Electrical impubses are transferred from one neuron to another via a synapse. Synapses can be electrical or chemical. In response to an electrical stimalus such as an action potential the presynaptic neuron in a chemical synapse releases a neuro- transmitner across a small space between the two neurons known as a symaptic cief. Neurotransmitiers may have excita- ory...

1. What triggers the opening of each of the different channels: ligand-gated K+ channels, ligand-gated Na+ channels, ligand-gated Cl- channels, voltage-gated Na+ channels, voltage-gated K+ channels, voltage-gated Ca2+ channels. 2. What happens to membrane potential in the immediate area where the channel is located when the channel opens and ions flow through? 3. Since graded and action potentials happen in different locations on the neuron, explain what has to happen to link these different events together.

4. There are a variety of receptors and second messenger systems in cells that in many cases exhibit cross-talk with each other (the activation of one can influence the behavior of another). Given this fact understanding how ligand activated receptors works is not as easy as presented in your book or in class. a. There are a number of different ligands that interact with their respective receptors. How do receptors for testosterone, ferro transferrin and Fibroblast Growth Factor differ from...

1. Calcium plays several roles in cells that are critical for second messenger signaling and overall cell function. Yet loss of calcium homeostasis can result in cell death. a. List three cellular responses to a rise in cytosolic calcium b. Calcium ionophores such as A23187 and Ionomycin can demonstrate that a loss of intracellular calcium can lead to cell death through necrosis. Explain this statement. c. How is calcium important to the IP3/DAG pathway and why is this a two...

MEK is second messenger. Second messengers transmit and amplify the signal received by receptor –ligand interactions on the outside of the cell. Assume that the cancer cell has a mutation causing a constitutively active MEK (on all the time). Design a drug that acts as either a competitive inhibitor, allosteric inhibitor, or antagonist that would specifically inhibit this phenotype. Explain the Kd/Km of your drug for your chosen target. Explain the type of inhibition you will use. Explain how your...

You are studying a ligand-gated ion channel. The ligand is a neurotransmitter. Upon binding the neurotransmitter, the ion channel opens and Na+ flows into the cell. The receptor is found on the dendrites of frog neurons. You are going to use one of the patch-clamp variations to study the effect of (1) the neurotransmitter and (2) second (and separately) the effect of an antagonist. Explain the patch-clamp technique variation you would use and why. Explain how you will study the...

ln(k) = -E_a/R 1/T + ln(A) A plot of ln (k)versus 1/T result in a straight line with a slope = -E_a/R. The value of E_a can then be calculated using the value of R and to the slope of the line. This experiment uses the Arrhenius equation, which relates the temperature and specific reaction rate constant to determine the activation energy for the crystal violet reaction. The reaction will be performed at different temperatures. Once the order of reaction...
