Question 5What would occur if the concentrations of GAP and GEF were reversed? (high [GEF] in cytoplasm, and high [GAP] in thenucleoplasm)nuclear import and export would occur normallyexported cargo proteins would be prematurely released in the cytoplasmimported cargo proteins would not be released in the nucleoplasmall Ran GTP in the cytoplasm would be hydrolyzed

The plasma membrane has a hydrophobic interior due to the two present in each phospholipid found in the phospholipid bilayer of the cell membrane. The plasma membrane allows some molecules to cross but not all. Therefore, the plasma membrane is said to be Molecules that are nonpolar and hydrophobic will cross the membrane with ease by Does this process require energy? When molecules move across the plasma membrane by passive transport, they will move down or with the_ from an area of concentration to an area of. concentration. Polar, hydrophilic molecules and charged ions will move across the plasma membrane by the process of_ This does not require energy, but it does require a A special case of diffusion is known as which is the movement of water across the plasma membrane.

Ran is a major player in the process of nucleocytoplasmic transport via the nuclear pore. Because net Ran movement simply follows a concentration gradient, what maintains the Ran gradient across the nuclear membrane? Options: the concentration levels of cargo in the nucleus to be exported GTP concentrations in the nucleus the correct positioning of the GEF and GAP with respect to the nuclear envelope the interaction of exportin and importin with their cognate substrates none of the above

It is assumed that the K+1 can pass through the cell membrane (the K+1 transport protein is open). Answer the following true or false questions. 1. K+1 will diffuse through the membrane down its concentration gradient due to Kinetic Theory 2. Movement of a solute through the membrane is called dialysis 3. K+1 will move out of the cell
