Textbook Question
Chapter 21, Problem 24RQ
Using what you have learned about epithelial transport, draw a picture of the salivary duct cells and lumen. Arrange the following membrane channels and transporters on the apical and basolateral membranes so that the duct cell absorbs Na+ and secretes K+: ENaC, Na+-K+-ATPase, and K+ leak channel. With neural stimulation, the flow rate of saliva can increase from 0.4 mL/min to 2 mL/min. What do you think happens to the Na+ and K+ content of saliva at the higher flow rate?

Hello, I do not understand this. May I get help with this physiology question? Steps leading to the correct answer would be helpful.
Question: Pierre G. just accidentally ingested a substance in the lab that he shouldn't have (that's what he gets for eating in the lab!). He quickly googles what to expect, and he sees that the substance blocks the Na+/K+ pumps on the basolateral membrane of his small intestine's enterocytes. Yikes! He asks you, his favorite physiologist, what to expect.
You tell Pierre the most likely outcome is… (see image)
Describe what happens if the food that reaches the duodenum contains a lot of fat and a lot of protein.
The answer must state, among other things: How is Gastric emptying − Hydrochloric acid secretion − Bile release − Pancreatic release (exocrine)s are affected by the respective stimuli (fat and protein) and how (ie increases or decreases the activity). What type of cell senses stimuli and how these cells react. The different signaling pathways (including the neurotransmitters involved) that control the different mechanisms affected by the respective stimuli. Feel free to draw
A patient came to a dental clinic with complaints of dry mouth and multiple dental caries lesions. In the course of collecting anamnesis, it was found that an allergic patient takes antihistamines that block the H2 histamine receptors of smooth muscle cells of the salivary glands. It is known that histamine is a mediator that stimulates the secretion of saliva. Explain the mechanism of action of these drugs if it is known that the next day after discontinuation of the drug, the patient's dryness disappeared. For this:
а) write the classification of inhibitors according to the mechanism of action
b) indicate what type of inhibitors the drugs are taken by the patient; confirm your conclusion in writing
c) guess what structure this drug may have
d) give a picture illustrating the action of this type of inhibitors.
