1The main component of a biological membrane is a [blank_start]phospholipid[blank_end] [blank_start]bilayer[blank_end]. [blank_start]Hydrophilic[blank_end] heads face out while [blank_start]hydrophobic[blank_end] tails face in. The model is called a "[blank_start]fluid[blank_end] [blank_start]mosaic[blank_end] [blank_start]model[blank_end]" because there are several components making up the membrane, which all move laterally relative to each other.
- Aphospholipid
- Bbilayer
- CHydrophilic
- Dhydrophobic
- Efluid
- Fmosaic
- Gmodel
2The molecule MOST responsible for plasma membrane fluidity is...
- APhospholipid
- BCholesterol
- CProtein channel
- DIntegral protein
- ECytoskeleton
3A protein with a carbohydrate attached to it is called a [blank_start]glycoprotein[blank_end].
- Aglycoprotein
4Which of the following statements are true about cell surface membranes? Select all that apply.
- APartially permeable.
- BRegulate transport into/out of cells.
- CPrimary organelle involved in modifying and packaging polypeptides.
- DDisplaying antigens.
- EReaction site for some metabolic pathways.
- FSite of glycolysis.
5All biological membranes are roughly the same as they fulfill the same role.
- ATrue
- BFalse
6Which of the following statements correctly describe the effect of temperature on fatty acids? Select all that apply.
- AAs the temperature decreases, saturated fatty acids become less fluid.
- BAs the temperature decreases, saturated fatty acids become more fluid.
- CAs the temperature decreases, unsaturated fatty acids become more fluid.
- DAs the temperature decreases, unsaturated fatty acids become less fluid.
7Which of the following statements correctly describe the effect of temperature on biological membranes? Select all that apply.
- AAs the temperature increases, the membrane becomes more fluid.
- BAs the temperature increases, the membrane becomes less permeable.
- CAs the temperature increases, membrane components move around more.
- DAs the temperature increases, cholesterol works to make the membrane more fluid.
8Which of the following can denature proteins in biological membranes?
- AHigh temperatures
- BLow temperatures
- CExtreme pH
- DAcetone
- EEthanol
- FWater
