Which cell type would you expect to have the most active lipid synthesis in the centralnervous system?

Guillain Berré syndrome is a demyelinatig disease in the peripheral nervous system. You would expect the cell type affected by this disease to be:

Destroying neurons in the dorsal (posterior) root ganglia would immediately kill:

(10 points) In muscle, which lacks obvious , Ca2+ enters the cell through Ca2+ channels and binds to on the SR to increase intracellular Ca2+. These ions then bind to , an evolutionary ancestor of troponin C, which activates . This enzyme then phosphorylates one of the two attached to myosin. This phosphorylation changes the position of the so that it can reach the thin filament which is made of polymerized . Contraction in this muscle type ends when an enzyme called a removes the phosphate group that had been added to the answer in Blank #7.

Where would you find a high concentrations of nucleic acids?

At what point in the accompanying diagram are the intracellular and extracellular Na+concentrations the same?

In an apparent assassination attempt in March 2018, Sergei Skripal and his daughter Yulia were found unconscious on a park bench in Salisbury, England. On June 30, 2018, Charlie Rowley and Dawn Sturgess fell ill in a nearby town. The cause in both cases was cetylcholinesterase poisoning by Novichok. This nerve agent, which was developed in the Soviet Union in the 1970’s, permanently inactivates the enzyme acetylcholinesterase.  Following the initial effects of Novichok, the ligand-gated ionotropic channels become desensitized so that:

This question isn’t graded – it is just a reminder that if you used scratch paper, you need to show it to your webcam before you submit this exam! 🙂

Upper motor neurons release neurotransmitter onto the input region of neurons in the:

On December 31 of the current year, State Construction Inc. (“the company”) signs a contract with the state of West Virginia Department of Transportation to manufacture a bridge over the New River. The company anticipates the construction will take three years.   The company’s accountants provide the following details relating to the project:  Contract price,  $624 million Estimated constructions costs (in total),  $480 million Estimated total profit,  $144 million During the three-year construction period, State Construction incurred actual construction costs as follows:  Year 1,  $  48 million Year 2,  $288 million Year 3,  $144 million (Actual total costs equaled the estimated total of $480 million.) Assume the contract meets the criteria for revenue recognition over time, and State Construction uses the cost-to-cost method to recognize revenue. Which of the following represents the amount of revenue State should recognize in Year 1, Year 2, and Year 3, respectively?
