Ran and Rab are both involved in transport of proteins in the cell. Match the function with the correct protein.v Involved in nuclear import/exportA. Ran GEFv When bound to GTP, binds import receptor, andB. Ran GAPreleases cargo into nucleusC. Rabv Plays a role in targeting vesicles to correct membraneD. Ranv When GTP is hydrolyzed releases vesicle and effector

Which statement is not true of endoplasmic reticulum? There is smooth and rough endoplasmic reticulum It is found in all living cells. Rough ER has ribosomoes bound to it. Proteins are transported and modified within it Proteins cam be targeted for ER transportation
If a membrane protein is described as "integral" what does that word refer to? A) super important; plays a key function B) It is bonded to a non protein molecule like a sugar chain or lipid C) It must be an ID tage/ cell recognition protein D) It is strongly integrated/ embedded into the membrane likely spanning the entire width

What would happen to nuclear transport if you removed all of the Ran-GAP? For a while nuclear import receptors will still deliver cargo to the inside of the nucleus Nuclear import receptors will be loaded with RanGTP and will gradually stop binding to the proteins with NLS signals Nuclear export receptors will no longer deliver their cargo to the outside of the membrane and will probably shuttle in and out of the nucleus full of cargo Ran-GDP will no longer be made All of the above
