Unit Membrane Concept - The molecular structure of cell membrane is still not clearly known. Several models have been proposed from time to time to explain its structure based on its physico-chemical properties. In the year 1935 Danielli and Dawson proposed that the cell me..

Boil egg white in distilled water till a cloudy suspension is obtained. Cool it and divide the mixture into five equal portions in separate test-tubes. Label them A to E. Add different substances to each of the five tubes as shown in the table below and explain the observations: Test-tube A..

It is present in both plant and animal cells. It is living, elastic and made of proteins and lipids (fats). Its function is to provide a mechanical barrier for the protection of the inner cell contents and to regulate the movement of molecules in and out of the cel..

The plasma membrane or cell membrane surrounds the cell contents in all types of cells. It is a multipurpose covering composed of phospholipids and proteins..

The plasma membrane or cell membrane surrounds the cell contents in all types of cells. It is a multipurpose covering composed of phospholipids and proteins. fig. 16.4 - Cell Membrane Apart from the plasma membrane, an eukaryotic cell also shows int..

How does the neuroendocrine control work? The hormones are released in very small quantities, yet they can cause widespread dresponses in cells or tissues all over the body. These responses in cells or tissues all over the body. These responses can be quite specific and selective in different cell..

There is an increase in the amount of collagen proteins deposition in the intercellular spaces. This influences the permeability of cell membranes, affects the speed of diffusion of substances in and out and significantly influences the process of agei..

Fluid Mosaic Model - In the year 1972 Singer and Nicolson proposed a model for explaining the membrane structure, taking into account all the known facts. According to this model, cell membrane consists of a highly viscous fluid matrix of a bilayer of phospholipids having globul..

Summary - The term biomembrane is used to describe the plasma membrane (cell membrane) and the membranes that surround the various cell organelles. The plasma membrane forms a protective covering around the cell to maintain its size and shape. In addition, it..
