Answer to Practice Problem #3 for Passage of Xenobiotics Across Biological Membranes Tutorial:

 

False. While it is true that ethanol is non-ionizable, which means pH does not determine the region of the GI tract for most favorable for absorption, it is still more extensively absorbed from the small intestine. This is because the small intestine has a surface area several orders of magnitude greater than that seen in the stomach.
