, b. Changing the concentration of saturated fatty acids on
phospholipids will have little or no effect on membrane
fluidity. Only changes in unsaturated fatty acids will have
an effect.
c. Glycoproteins are found on the extracellular surface of cells
d. Transmembrane proteins are integral, such as receptor
tyrosine kinases e. Proteins from one side of the membrane
bilayer can move to the other side of the bilayer
8. Which of the following is FALSE regarding all G-proteins in signaling?
a. They can bind either GTP or GDP
b. They can hydrolyze GTP
c. They are regulated by ligand binding, but indirectly
d. They can bind phosphotyrosine
e. They can cause amplification of the original signal in the
pathway
9. Which of the following is not transferred in a Group Transfer
Reaction from ATP?
a. Adenosine monophosphate
b. A phosphoryl group
c. Pyrophosphate
d. Adenine
e. All of the above are transferred in Group Transfer Reactions
from ATP

recognized ones) that does not operate using proteins located in the
plasma membrane?
a. Adhesion receptors
b. G-protein coupled receptor
c. Steroid hormone receptors
d. Tyrosine kinase receptors 12. What structural form of DNA
