Cell membrane 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 cell...

It is a thin, elastic, selectively permeable membrane found internal to the cell wall. It is composed of phospholipids, proteins and polysaccharides. The plasma membrane is the site of most of the metabolic pathways. Certain structures are found associated with plasma ..

Plasma Membrane - 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 eu..

The cell membrane and the membranes of various cell structures exhibit the same structure and as such perform the same functions. However, the amount and arrangement of phospholipids and proteins varies in different cells and organelles. This variation accords a specif..

Proteins found in a biological system with definite configuration and biological acts is called a native protein. Denaturation is a process by which the native form of protein structure is disorganized. This causes drastic changes in a protein molecule. Denat..

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 membrane is made up of a lipid ..

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- Te..

These are lipids, usually phospho-lipids which contain a protein molecule. They occur in the cell membrane. They are also found in milk and egg yol..
