Question
Chapter 27.2, Problem 8AYP
Summary Introduction
To analyze:
Two mechanisms that are triggered by an increase in the osmolality of the extracellular fluid.
Introduction:
The body’s water content is regulated so that the total volume of water in the body remains constant. Thus, the volume of water taken into the body is equal to the volume lost each day.

What two mechanisms are triggered by an increase in theosmolality of the extracellular fluid?
When the kidneys filter plasma, the filtered glucose is reabsorbed from the renal tubules and is not passed in the urine. However, glucose can appear in the urine when the blood sugar is exceptionally high.
Given that glucose is reabsorbed by carrier-mediated transport, what functional aspect of carrier-mediated transport does the appearance of glucose in urine demonstrate? Explain.
Below find the structures for ibogaine and cocaine.
Ibogaine and cocaine inhibit the dopamine active transporter (DAT). This transporter is a secondary active transporter, and depends on the primary active transporter Na+/K+ ATPase. Ibogaine had a Kι = 2 μM, and cocaine a Kι = 0.64 μM respectively.
(a) Define secondary active transport.
(b) Is ibogaine an effective treatment for cocaine based on DAT binding?
