BiologyCellular processes and structureASWJEC Created by: sophiee96Created on: 11-11-12 12:03 Where does the exchange of substances take place? Across the cell surface membrane 1 of 11 Is the cell surface membrane selective? Yes 2 of 11 What does the membrane consist of? A bilateral of phospholipid molecules 3 of 11 The phospholipid is arranged so the hydrophilic head faces what? Either the cytoplasm or the outside of the cellt 4 of 11 The hydrophobic tails do what? Meet in the middle of the membrane 5 of 11 Across the expanse of phospholipids there are a number of what? Protein molecules 6 of 11 What does it mean if the protein molecule is intrinsic? It spans the complete width of the membrane 7 of 11 What is the name given to a protein that is partially embedded in the membrane? Extrinsic 8 of 11 What does a phospholipid molecule consist of? A hydrophobic tail and a hydrophilic head 9 of 11 What does the protein channel do? Transports specific substances into the cell 10 of 11 What is the cell surface membrane made mostly of? Proteins and phospholipids 11 of 11
