Question
Chapter 3, Problem 4CT
Summary Introduction
To answer:
The effect of cells in the hypertonic state by the ions produced in the digestive tract under the influence of bacterial toxins. Also explain the effect of the patient’s water balance under a hypertonic state.
Introduction:
One of the remarkable functions of the cytoplasmic membrane is selective permeability. Depending upon the state of the cell, the nutrients are brought into the cell and the wastes are exported outside the cell. The passage of molecules inside and outside of the cell is under the control of the cytoplasmic membrane.

Match the definitions with the words:
Direct Diffusion, Facilitated Transport, Active Transport
a) passive movement of molecules through a protein channel, down the solute's concentration gradient
b) using a vesicle to move many molecules into a cell
c) movement of molecules through a protein transporter, requires ATP, against the solute's concentration gradient
For the following scenario you must draw the situation depicted, indicate which solution is hypertonic, hypotonic or isotonic (as applicable), and then show with arrows which way water will move. Then you must write your response in complete sentences, thoroughly explaining and justifying your arrows.
a. Ouch! Sore throat! It is so swollen that it is sore and it is difficult to swallow. And you have an oral presentation today. Better gargle with salt water to reduce the swelling! Explain why this age old technique really works, by using the concept of osmosis.
If a dialysis bag containing 1% sucrose is placed in a beaker containing 25% sucrose,
what would you expect to happen?
(hint: only water can move in and out os the bag through osmosis, sucrose is too
large; this is a hypertonic environment)
A) there will be a loss in weight of the bag due to water leaving the bag
B) there will be a gain in weight of the bag due to water moving into the bag
C) the weight of the bag will remain the same, with water moving in both
directions equally
D) sucrose will break down and will move into the bag, increasing the weight of
the bag
