Document Summary
Determined by plane of division and degree of separation after division. Tension between negative charge on inside of cell and positive charge on outside of cell. A proton can move inside the cell and make atp. Don"t want the membrane to become solid when cold. Don"t want membrane to be liquidy and runny when hot. Sit loosely on the outside of the membrane. Component of both gram negative and gram positive cells. Made up of mesh like polymer consisting of: Alternating sugar sheets that are linked on top of each other with amino acids. Amino acids bind to the nam sugar and link sheets of sugars together. Amino acids: l-alanine, d-alanine, d-glutamic acid and l-lysine. The link between the sugars = beta 1,4 bond. Direct linkage: amino acids bind directly to the polysaccharide backbones. Indirect linkage: amino acids use a bridge to link another amino acid chain which links the sugar sheets together.
