7: Membranes (part 3: The Fluid Mosaic Model) Quizellenjmchenry2020-03-20T15:22:22-04:00 Please sign up for the course before taking this quiz. What is the job of the enzyme Flippase?1 turns transmembrane proteins upside down. Takes two phospholipids and has them trade places. Turns the hydrophobic tails towards the outside of the membrane. moves a phospholipid from one side of the bilayer to the other. What process is the enzyme Flippase especially helpful for?1 Moving lipid rafts. Endocytosis. Ion exchange. Sending messages. Where might you find a higher concentration of cholesterol in a membrane?1 In a lipid raft. In the enzyme Flippase. In an oligosaccharide. In a transmembrane protein. Lipid rafts help proteins that belong together, stay together.1 True False Only the cells in your reproductive system have “self” ID tags.1 True False What keeps transmembrane proteins in the membrane?1 They have a large hydrophilic region in their middle. They have a hydrophobic 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 "Sugar" "Protein" "Big" "Signal" All transmembrane proteins are integral proteins, but not all integral proteins are transmembrane proteins.1 True False Peripheral proteins1 are embedded in the membrane, all the way from one side to the other. don't go inside the membrane. 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. When a protein passes all the way through a membrane from one side to the other, it is called a/an1 peripheral protein lipid raft transmembrane protein integral protein 6: Membranes (part 2: Membrane Transport) 8: Proteins (part 1: Amino acids) Back to: 7: Membranes (part 3: The Fluid Mosaic Model)
