In this article we will discuss about the Plasma Membrane:- 1. Subject Matter of the Plasma Membrane 2. Chemical Composition of Plasma Membrane 3. Specialized Structure 4. Functions. Subject Matter of the Plasma Membrane: The protoplasm of the cell is bounded by an exceedingly thin elastic, semi-permeable living limiting membrane called the plasmalemma or plasma membrane or cytoplasmic membrane or [...]
The following points highlight the top two types of membrane models. The types are: 1. Lamellar Models 2. Micellar or Sub-Unit Models. Membrane Models: Type # 1. Lamellar Models: (I) Lipid Bilayer Hypothesis: Overton (1895) suggested that the cell membranes contain lipids. This conclusion was based on the fact that fat solvents dissolved the membrane easily and fat soluble substances [...]
In this article we will discuss about the Transport of Ions and Other Molecules through Biological Cell Membrane. The living organisms can be resolved into organs, glands, tissues, cells and organelles. It is very interesting in biology to know how solutes and water get into and out of cells and organelles. Most attention is to be paid to erythrocytes and [...]
