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.

The principles of osmosis are used in food preservation. Certain foods are stored in strong salt solutions (brine) or in syrups to prevent infection by microbes.
a) Explain how the principles of osmosis apply to this situation.
b) What effect will these solutions have on the micro-organisms?
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
Isotonic, hypotonic, and hypertonic IV (intravenous) fluid
solutions are widely used in the healthcare setting. As a
possible health care professional, you must know how each of

a) When does each type of solution must be applied to a
patient?
b) What does each type of solution do the cells?
