Show transcribed image text You are interested in further understanding the signal transduction pathway that controls the production of Fig. 1. A protein important for regulating cell size. Activation of the TRK receptor leads to activation of the GTP-binding protein, Ras, which then activates a protein kinase that phosphorylates the 5ZE transcription factor. SZE only interacts with the phosphorylates the 5ZE transcription factor. 5ZE only interacts with the nuclear transport receptor when it is phosphorylated. 5ZE is a gene activator for the Pig 1 gene. This pathway is diagrammed in Figure Q16-50 Normal cells grown under standard conditions (without ligand) are 14 mu m in diameter while normal cells exposed to TKK ligand are 10.5 mu m in dimater. Given this situation, which of the following conditions do you predict will more likely lead to smaller cells? Addition of TRK lignad and a drug that stimulates the GTPases activity of Ras Addition of TRK lignad and a drug that inhibits the activity of the phosphatase that acts on 5ZE addition of TRK lignad and a drug that stimulates the degradation of Fig 1. Which of the following statements is true? Phospholipids will spontaneously form liposomes in nonpolar solvents. In eukaryotes, oil membrane-enclosed organelles are surrounded by one lipid Mayer. Membrane lipids diffuse within the plane of the membrane. Membrane lipids frequently flip-flop between one monolayer and the other. A bacterium is suddenly expelled from a warm human intestine into the cold world outside. Which of the following adjustments might the bacterium make to maintain the same level of membrane fluidity? produce lipids with hydrocarbon tails that are longer and have fewer double bonds. Produce lipids with hydrocarbon tails that are shorter and have more double bonds. Decrease the amount of cholesterol in the membrane. Decrease the amount of glycolipids in the membrane. New membrane phospholipids are synthesized by enzymes bound to the side of the membrane. cytosolic, mitochondrial luminal, Golgi cytosolic, endoplasmic reticulum extracellular, plasma
