Unformatted text preview: • Ganglioside lipid + specific sugars o Gangliosides are found in high concentration on nervous tissue membrane • Plasma – allws cell-cell communication • ECM (extracellular matrix)– surface layer surrounds cell ie. Glycocalyx ~ large polysaccharides proteins, proteglycans (allow cells to move past each other or have flexibility ie cartlidge) • Signal transdunction = external signal ex. Hormone or a cytokine that binds to a cell membrane or plasma membrane receptor that then induces a molecular cytoplasmic signal to be made and therefore will affect the inside of the cell (ie. Turn protein or genes on and off) o Transfer of a external signal into an internal signal •...
