Which of the following would be the correct cellular pathway from DNA to the cell secreting a protein?

• DNA > mitochondria > lysosomes > cell membrane

• DNA > vacuole > ribosomes > cell membrane

• DNA > Smooth ER > lyosomses > cell membrane

• DNA > Rough ER > Golgi Bodies > cell membrane

The ability of phospholipids to form membranes

• Depends on their secondary nature

• Depends on their amino acids

• Because they are awesome sauce

• Is related to their polar and nonpolar properties

Which of the following is NOT true of a hypotonic environment?

• Fresh water

• Plant and animal cells will both burst

• The net movement of water is entering the cell

• The outside environment contains less solute than the internal cellular environment

A membrane protein with hydrophobic regions

• Would be more fluid than those lacking hydrophobic regions

• Would likely be able to span the membrane as an integral protein

• Would be a peripheral protein

• Would be highly soluble in water

Integral protein channels in the plasma membrane are required for

• Simple diffusion only

• Osmosis only

• Facilitated diffusion only

• Facilitated diffusion and active transport
