MOD 14 PLASMA MEMBRANE

• PLASMA MEMBRANE a thin semi-permeable membrane that sorrounds the cytoplasma of a cell
• 3 types of CELL MEMBRANE LIPIDS

  PHOSPHOLIPIDS

  CHOLESTEROL

  GLYCOLIPIDS
• Types of CELL MEMBRANE PROTEINS

  •PERIPHERAL MEMBRANE PROTEINS

  •INTEGRAL MEMBRANE PROTEINS

  •STRUCTURAL PROTEIN

  •RECEPTOR PROTEIN

  •GLYCOPROTEINS
• Phospholipids lipid bilayer which is semi permeable allowing only certain molecule to diffuse across the membrane
• Chlesterol selectively dispersed(contribute or diffuse) between membrane phospholipids
• Cholesterol help to keep membrane from becoming stiff by preventing phospholipids from being too closelybpacked to each other
• Glycolipids located on cell membrane surfaced and have carbohydrate sugar chain attached to them.
• Glycolipids helps cell to recognize other cells of the body
• Peripheral membrane proteins are exterior and connected to the membrane by interaction with other protein
• Integral membrane protein transmembrane proteins are exposed on both sides of the membrane
• Structural protein help to give the cell support and shape
• Receptor proteins helps cell to communicate with their external environment through the use of hormenes, neurotransmitters, and other signaling molecules
• Glycoproteins have carbohydrate chain attached to them. They are embedded into cell membrane and help in cell to cell communications and molecule transport across the membrane
• Glycoprotein They are embedded into cell membrane and help in cell to cell communications and molecule transport across the membrane
