Document Summary
4 multipass transmembrane protein two of each the cup forms a pore. Eukaryotes, almost all are exporters; while prokaryotes, importers and exporters exist. dimerization of atp-binding domains: two atp molecules, one for each abc form protein protein complex, cauising conformational change in the protein thus opening on otherside of the membrane. Bacteria harmful to us because they export this lipid a. 5 sequester toxins removed by leaf shedding . Vacuole of leaf cells get inflated with toxins, and get rid of leaf to lose toxins. 6 mdr1-possesing cells can survive chemotherapy by exporting it out of the cytosol, so the few that survives. Also has normal function in normal body cells. Cftr cystic fibrosis caused by calcium levels. 7 a) transporter proteins all change conformation as they transport molecule across membrane. Channels are pores, can open and close, but this is not conformation change.
