BILDl Halpain Problem Set C Campbell Chapters 78 1 Endomembrane System a Correctly order the path of a secretory protein from synthesis to secretion Answers may be used more than once 1 Plasma Membrane II TransGolgi III ER lumen IV CisGolgi V Vesicle b A membrane vesicle has left the Golgi and is poised to deliver a neurotransmitter receptor which is a transmembrane protein to the plasma membrane via exocytosis The neurotransmitter that activates this receptor must bind to a site on the receptor s extracellular domain Use a simple sketch to illustrate the membrane fusion events that deliver the receptor in the correct orientation 2 Transport a For each of the transport mechanisms below that carry materials across biological membranes indicate whether ATP is used whether the molecule moves up or down its concentration gradient whether a transport protein is required and the chemical nature of particles transported are they small or large hydrophobic or hydrophilic nonpolar or polarcharged Complete the chart a Mechanism Concentration Used Transported Gradient diffusion b Explain brie y how cotransport works 3 Osmosis a Indicate the net ow of water Membrane is permeable to water only b C Sucrose 04M Indicate the net ow of water The membrane is permeable to water only
