What would happen to a neuron if it were exposed to tetrodotoxin?
1. Be specific regarding tetrodotoxin’s effect on the structures present in the membrane of this cell.
2. Considering your answer above, what effect would that have on the neuron’s ability to communicate
Homework Answers
Tetrodotoxin is neurotoxin which inhibits(1) sodium channels in the neuron membrane, that is it blocks voltage-gated ion channels in the axon so action potential cannot move along the neuron so action potentials cannot propagate so cells cannot communicate each other.

You are studying a neuron from a newly discovered alien species, inside the neuron are many positive charged proteins, P+ Outside the neuron are high concentrations of two negatively charged ions, X- and Y-. Another ion, Z+, also exists both inside and outside the cell (assume the rules of cell membranes, permeability, electric charges and ion channels are the same as a regular neuron on Earth). 1. In its default state, the alien neuoron's membrane is permeable only to Z+....

What would happen to the neuron if the Na- K ATPase activity was completely inhibited? O a. The resting potential wouldn't be restored after the action potential Ob. Repolarization of the membrane wouldn't appear. c. The resting potential would be restored too fast after the action potential. Od. The action potential couldn't be generated.

Based on your excellent understanding and extensive knowledge of chemical synaptic transmission, EXPLAIN what would happen in response in each hypothetical situation below….Assume you have an experimental set-up with two neurons connected via a chemical synapse – Neuron A is presynaptic and Neuron B is postsynaptic. Also assume that there is a stimulating electrode in Neuron A that brings it to threshold and produces an EPSP in Neuron B. In your answers, include all relevant events between this stimulus and...

Resting potential has been drawn for you. Continue that line to show what would happen to membrane potential in the POSTsynaptic muscle cell if the person was exposed to cyclosarin. Cyclosarin prevents acetylcholinesterase (the enzyme that breaks down the neurotransmitter) from breaking down acetylcholine (the neurotransmitter).

1. What would happen to a gene if the stop codon (UAA, UAG, or UGA) were mitated so that the first position in the codon became a “C” (CAA, CAG, CGA)? a) the protein product of the gene would be similar than normal b) either the immature RNA transcript or the mRNA will be degraded by nonsense mediated RNA decay c) its mature messenger RNA would be lengthened d) its immature RNA would be lengthened 2. Without a promoter region,...

Briefly describe three (3) specific and different examples of cooperation between the innate (I) and adaptive (A) branches of the immune system. The following example shows the format to use for each of your three responses.Example: IgM (A) binds to the pathogen membrane and initiates the classical complement-mediated (I) membrane attack complex, leading to pathogen destruction. 14. You have developed an experimental vaccine to prevent infection by Hanta virus. To test the effectiveness of the vaccine, you recruit individuals to...
