All living cells have a cell membrane and it is probably the most important organelle of a cell. The cell membrane is composed of a phospholipid‚ proteins and carbohydrates. The phospholipids are arranged in a bilayer with the hydrophilic ends facing out and the hydrophobic ends facing the inside of bilayer. Membranes can contain phospholipids with different fatty acids which affects the strength and flexibility of the membrane. There are two different proteins in cell membranes. One is a protein

There are many kind of cell membrane disease‚ There are : Cystic Fibrosis Cystic Fibrosis is a disease that cause by gene mutation of CFTR Protein. CFTR it’s stand for Cystic fibrosis transmembrane conductance regulator. This disease causes too much production of thick mucus‚ then the mucus will blocked the ion transport in epithelial cells that line the passageways of the lungs‚ pancreas‚ and other organs.

Assignment 1: Cell Membranes and Temperature Background Theory Beetroot contains betalain pigments within it’s vacuole‚ which gives it it’s purple-red colour‚ it’s this pigment which leaks out as the beetroot is heated and the cells membrane begins to break down. The practicals aim is to show the effect of temperature on the cell membrane by observing the colour change of the water the beetroot was placed in. The cell membrane is important as it controls the substances enters and leaves the cell with
