3		Where do proteins go next from the rough endoplasmic reticulum if they are to be transported from the cell?
			A)	They enter the Cis face of the Golgi apparatus where they are modified and packaged into secretory vesicles.
			B)	They enter the Trans face of the Golgi apparatus and are expelled from the Cis face.
			C)	They enter the cisternae of the Golgi apparatus where it may take up to a year to correctly modify the protein for excretion.
			D)	They enter the smooth endoplasmic reticulum where they are packaged for secretion from the cell.
4		What is one reason why proteins are transported within vesicles inside the cell rather than being transported without vesicles?
			A)	to prevent them from folding into their 3-dimensional shapes
			B)	to minimize the possibility that they will gather additional amino acids
			C)	to prevent them from interacting with other proteins or components of the cell
			D)	to keep them from hydrolyzing and disassembling

5		If the left side of the beaker has a greater concentration of urea than does the right side, what statement is true?
			A)	Water will leave the left side of the beaker by osmosis and join the right side of the beaker.
			B)	Water will be exchanged between both sides of the beaker, but there will be no net change in the amount of water on either side.
			C)	Water will be exchanged from the left side of the beaker to the right by facilitated diffusion.
			D)	Water will leave the right side of the beaker by osmosis and join the left side of the beaker.
6		What is the effect if the solute is polar?
			A)	The polar solute repels the water molecules.
			B)	The polar solute binds up the polar water molecules, effectively increasing the osmotic pressure on the left side of the beaker.
			C)	The polar solute dissolves more readily in the water and has no effect different from a nonpolar solute.
			D)	The polar solute does not dissociate in water to any appreciable degree.
