PLASMA MEMBRANE
NOTE: This is lifted from the site of Sir Baggy .
Plasma Membrane
Plasma membrane is the outer membrane of a cell. Though it is so thin, it screens out substances that enter and get out of the cell. This function is necessary to maintain the cell's precise chemical environment. Likewise, as a membrane, it separates the cytoplasm from its environment so that the cell can maintain its own integrity as a living component.
In this module, you will review the basic relationship between structure and function, and we will use plasma membrane as a starting model for this study. Thus, at the end of the module, you should be able to describe the structure of plasma membrane, and related this structure to its function. You should also be able to evaluate the importance of these structures and functions in maintaining life including that of human beings.
Below is the list of topics and resource materials for this module. Click on the topic to access the material.
1. What is plasma membrane?
2. The Fluid Mosaic Model
3. Plasma membrane structure
4. Plasma membrane functions
5. Plasma membrane and life
a. Bioelectricity of membranes
b. Pharmacokinetics
c. Intracellular pathogens and maintenance of vacuolar compartments
Activity

1. what is the problem/s presented?
2. what are the facts associated with the problem/s?
3. what did the authors do to resolve the problem/s?
4. what did they say about their findings?
5. what did other literature say about the authors' findings?
