Question
Chapter 49.2, Problem 2CS
Summary Introduction
To determine: The special property of epithelial cells that is demonstrated by their multiple responses to aldosterone.
Introduction: Epithelial membrane is the membrane that is present on the outermost surface of all the different organs of the body and in blood vessels. The epithelium is usually made up of squamous, cuboidal or columnar cells. In the excretory system, transport, selective absorption and secretion are the main functions of the epithelial cells.

Scenario: Chet H. has been feeling weird lately and so he has some medical tests conducted. The doctors tell him that the dicarboxylate co-transporters on the basolateral side of his proximal tubule cells not working correctly. He comes to you to ask what the consequences of this condition will be: You tell Chet that the most direct problem will be: (see image)

The principle depends upon finding the concentration of sucrose that would cause no change in weight of the tissue before and after an incubation period in the solution. This concentration may be assumed to have a water potential equal to that of the tissue.arrow_forward
