Peripheral proteins1 are embedded in the membrane, all the way from one side to the other. are the same as integral proteins. are embedded in a membrane, but don't go all the way through from one side to the other. don't go inside the membrane. What keeps transmembrane proteins in the membrane?1 They have a hydrophobic region in their middle.. They have a large hydrophilic region in their middle. They are anchored in by many other proteins. They have an ionic charge that is attracted to the phospholipid tails. “Glyco” is Greek and “sacchar” is Latin for1 "Protein" "Signal" "Big" "Sugar" What is the job of the enzyme Flippase?1 Takes two phospholipids and has them trade places. turns transmembrane proteins upside down. moves a phospholipid from one side of the bilayer to the other. Turns the hydrophobic tails towards the outside of the membrane. Where might you find a higher concentration of cholesterol in a membrane?1 In a transmembrane protein. In an oligosaccharide. In a lipid raft. In the enzyme Flippase. Only the cells in your reproductive system have “self” ID tags.1 True False All transmembrane proteins are integral proteins, but not all integral proteins are transmembrane proteins.1 True False What process is the enzyme Flippase especially helpful for?1 Ion exchange. Endocytosis. Sending messages. Moving lipid rafts. Lipid rafts help proteins that belong together, stay together.1 True False When a protein passes all the way through a membrane from one side to the other, it is called a/an1 transmembrane protein peripheral protein integral protein lipid raft 1: The water molecule 3: Lipids and glycerol Back to: 2: Carbon atoms and fatty acids
