Unformatted text preview: l is potentially using facilitated diffusion for glucose uptake? A B C D E for None of them. Which cells are potentially using active transport? A. B. C. D. E. 1 2 1 and 2 2 and 3 1, 2 and 3 Trend line 1 shows the uptake of a solute into a bacterial cell by active transport Which of the other three trend lines (A, B or C) might represent the uptake if ATP synthesis is inhibited before measuring the uptake. A B C D None of them is possible. Is possible to tell whether Leucine is being taken up by active transport? A. B. C. D. Yes, the rate of uptake is very fast Yes, the level of uptake would be lower if uptake was by facilitated diffusion No, the graph doesn’t show whether the rate slows with time or not No, the graph doesn’t show whether energy is needed or not Why can’t the cytoplasmic membrane resist osmotic pressure? A. B. C. D. E. The cytoplasmic membrane has too many types of molecules in it. The interactions holding the phospholipids together are very weak. Lipid molecules change shape when subjected to pressure. High pressure makes water more soluble in lipid. High pressure makes lipids more soluble in water. α-helices and β-pleated sheets are two common configurations of a protein's secondary structure. What is the main factor that determines which type of configuration forms, or if one forms at all? A. B. C. D. E. Hydrogen bonds between the protein's amino acids. The location of the protein in the cell. The covalent bonds between the amino acids that make up the peptide. The side chains of the amino acids that make up the protein. The type of cell the protein is in....
