Diagram/Essay Question: Provide a diagram and a narrative paragraph using your own words and sentence structure to fully answer the following question. Make sure to provide enough detail to address all points of the question. Diagram, illustrate, or describe in detail the process of glucose reabsorption across both membranes in the tubule cells and describe how it is linked to sodium reabsorption. Include the location in the nephron where it occurs, regulating hormones (if applicable), protein channel/pump up-regulation or down-regulation (if applicable), protein channel/pump activation or inhibition (if applicable), and ion movement (if applicable). Your answer should be detailed, comprehensive, and specific. Tip: You may want to use your scratch paper to diagram or illustrate your thoughts as you brainstorm your answer. If so, you can upload it as a file submission in the next question.

Neuron Action Potential – Part 2 This question is about what triggers the voltage-gated ion channels to open and close during an action potential. Take a look again at the graph of an action potential on the membrane of a neuron (given below). Describe what is happening in the voltage-gated sodium channels and the voltage-gated potassium channels during the point in time on your graph 1) when threshold is reached, 2) when +30mV is reached, and 3) when -80mV is reached. What are each of the two ion channels doing at each of these 3 points on the graph? Tip: remember that sodium channels have two gates and three states, whereas potassium channels have one gate and two states.

Diagram/Essay Question: Provide a diagram and a narrative paragraph using your own words and sentence structure to fully answer the following question. Make sure to provide enough detail to address all points of the question. Diagram, illustrate, or describe in detail the aldosterone system of control on fluid balance in the body. Your answer should include (but isn’t limited to) specific details about the stimulus, the receptor/control center, and the changes on the lumenal side and the basolateral side of the principal cells in the collecting tubule and collecting duct in response to aldosterone, and the net effect. Your answer should be detailed, comprehensive, and specific. Tip: You may want to use your scratch paper to diagram or illustrate your thoughts as you brainstorm your answer. If so, you can upload it as a file submission in the next question.
